It takes almost a minute before reading anything more than 7, but it does begin climbing steadily, though very slowly.
When it reaches I try to feed PLA through, it smokes and spits like an angry cat. It is obviously much hotter than I have checked that the thermistor is seated correctly and reseated it with the same result. What have I done wrong? Any troubleshooting ideas? Oh, one bit of info I forgot.
The thermistor reads a resistance of Mike Kelly Volunteer. Joined: Mar 7, Messages: Likes Received: Take it out and measure the resistance. It may be shorting against the heater block but that doesn't make sense for a resistance of ohms.
That's like PT range. Just pulled it out of the heater block. It's reading a resistance of Then put it back in, Joined: Mar 1, Messages: Likes Received: Thats a normal thermistor not a PT based on the photo.
He's probably leaving off the kilo in his measurement. What electronics board are you using for your clone? Are you certain that the balancing resistor is a 4. A balancing resistor of say, 1k would cause what you're seeing. It's one of the Ultimaker copies from China. This one to be specific. I am not certain about the resistor at all. Where are you connecting the thermistor on that board?
Unless I'm not seeing the thermistor inputs. It's plugged into "Temp 1". Did I make a mistake by assuming it would just work with the new sensor?Inadequate cooling is the most common cause of problems, accounting for nearly half of all issues reported to us. Consistent performance of the extruder is heavily dependent on having a sharp temperature differential between the nozzle and where the cold filament enters.
If the unit is not cooled properly, filament will melt too high in the unit and cause jamming. The entirety of the heatsink must be kept cool at all times during printing. For this to happen enough airflow must be directed at the heatsink, and that airflow must be distributed over the whole heatsink.
The use of the supplied 30mm fan and duct is highly recommended, the supplied fan has adequate airflow CFM and the duct is specifically designed to aim that airflow at the fins of the heatsink. An easy way to check that your heatsink has sufficient air flow is to simply feel the heatsink with a finger after a print has been running for some time. Be careful not to touch the heater-block, it will burn you instantly The entirety of the heatsink should be cool to the touch, including the bottom fins closest to the hot parts.
Like the heatsink and fan cooling your CPU, proper thermal conduction is necessary for the heatsink to work. In the case of your E3D hot end, the threaded heat-break tube should be snugly tightened into the heatsink otherwise the threads will not make sufficient surface contact to conduct heat. If you are printing in hot climates or continue to have issues, a liberal coating of thermal paste on the upper heat-break threads will ensure much better thermal contact with the heatsink.
Even with thermal paste the threads can vibrate loose and cause performance issues. To combat this heat up the heatsink with a heat gun and then thread in and tighten the heat break tube with two pairs of pliers.
The heatsink should contract around the heatbreak when it cools and ensure a solid connection. Choosing slicer settings is a bit of an art and everyone has their particular preferences as to how they print. The following guidance is to help people avoid common configuration pitfalls. A common issue is massively excessive retraction distances.
In direct configurations retraction of 0. We use around 0. For PLA we stick with retraction settings no higher than 0. Bowden configurations are more tricky as the amount of retraction needed is dependent on factors such as the length of tubing and the stiffness of the filament has more impact on the needed retraction.
A good starting place is around the 2mm mark, which you can increase if required.Replace Temp sensor for nozzle HICTOP 3D Printer
Retractions of 5mm or more are troublesome as they pull hot filament up into the cold areas of the hotend where they can freeze, adhere and jam. You should be able to print at both very high, and very low speeds with your E3D hotend, but you may need to adjust your temperatures.
Very high speeds will require higher temperatures in order to melt the filament quickly enough as it passes through the hotend. Very slow prints do not require as high a temperature. Debris, dust, scorched carbonised plastic, contaminants in your filament, all of these things can enter and accumulate in the hotend. Debris can then block or partially obstruct the very small hole in the tip of the nozzle.
This can be as subtle as high extrusion force, or thin ribbon like extrudate, or it can simply be a complete blockage of the nozzle where no plastic can pass through at all. There is a fantastic guide to unblocking nozzles present on the Bukobot website which shows a range of techniques and procedures. There are a huge number of filament vendors out there, to cater to all needs and budgets. The E3D hotends are designed to cope with and print the vast majority of filaments on the market.
Filament that is too big will have excessive friction in the hotend.Assembly of the E3D-v6 HotEnd should be an easy process that takes no more than half an hour.
Please follow the instructions on this page carefully to ensure that you assemble the HotEnd correctly. Screw Nozzle into the Heater Block into the end closest to the thermistor holes. Screw the Heat Break into the other side of the Heater Block so it is butts up against the nozzle. Gripping the Heater Block with a spanner, tighten the Nozzle with a second spanner. Do not over-tighten, we are going to tighten it up later when the heater block is hot. Simply slide the sensor cartridge into the heater block and use the supplied M3 grub screw to fix the cartridge into place.
Tighten the grub screw until it just touches up against the cartridge, then do one more half turn. It is important not to over-tighten the screw against the relatively soft copper cartridge, doing so can cause a range of annoying problems:.
If you have one, grab a multimeter and check the resistance of your heater cartridge against the table below. Expect your value to deviate a little from these, a difference of around plus or minus 5W is fine, however if yours is significantly off or you are concerned you have the wrong cartridge please get in touch. Insert the Heater Cartridge with the leads exiting the block the same side as the thermistor. Tighten the clamping portion of the heater block around the heater cartridge with the longer M3x10 screw.
As in the photo below you should be able to see very slight deformation of the heater block clamp as it wraps around the cartridge for maximum thermal contact. Note: The manufacturing process for heater cartridges often results in a degree of irregularity in both diameter and roundness. This is why we use a clamp, to accomodate this and ensure that in spite of the variation we get maximum thermal contact. If you do struggle to get a firm clamp on the cartridge try rotating it.
A washer under the head of the M3 screw will enable you to get a much higher clampling load. This improves heat-transfer from the heat-break threads to the heat-sink for slightly better thermal performance in marginal cases. The thermal compound should be spread evenly across the threads of the heat-break, only on the cold-side of the heat-break that screws into the heat-sink. The compound should not be used on any of the threads on the hot-side of the heat-break.
The small sachet of compound contains more than is needed for one HotEnd, so don't feel like you need to use all of it. Screw the HeatSink onto the HeatBreak by gripping the heatsink in one hand and the heater block in the other. It only needs to be tightened up hand-tight. Do not overtighten.Got a question or need help troubleshooting?

E3D had a very popular v5 hot end, but not being content with the design they looked at ways to improve upon it. The v5 is has an entirely metal hot end. The only non-metal components are on the bowden version which uses a plastic coupling with a bore through PTFE tube.Boku no roblox remastered codes september 2019
The v6 follows this trend, but the PTFE tube goes further into the heatsink, and butts up against the cold end of the heat break. What makes it unique? This video does a great job of going over all the enhancements of the v6, but I'll break them down as well: Height: The most obvious change is that the E3Dv6 is considerably shorter than the v5.
Previously from end to end of the direct feed E3D was a total height of 70mm while the bowden version required a total height of 82mm. In contrast the E3Dv6 is 63mm for both direct and bowden. If we compare this to the hexagon, we find the hexagon's direct drive is shorter at Bore: The short length of the E3Dv6 is due to the clever integration of pneumatic, push to fit connectors. This allows for 4mm tube to be fed through and into the heatbreak which has been bored out to fit it.
What this means is that there's a consistent 2mm of space for the filament from the moment it goes into the PTFE tube, to when it reaches the nozzle. If we compare this to the Hexagon, that uses a 1. This bore leaves only.
Thermistor The E3D brings about a new method of securing the thermistor. This is fine. However, when you do install the E3D thermistor you will need to adjust the thermistor type per instructions further down. Creates a solid connection that's very easy to swap in and out of. Now redoing wiring is not intimidating at all. Heater Cartridge: Unlike the v5 and Hexagon, the v6 moves away from securing the heater cartridge using a set screw.
Instead they use a clamp method to secure it. What this allows for is an increased point of contact between the heater block which reduces the power required and improves heat up times. This does have the obvious downside of a very large heater block, but puts the heater closer to the nozzle. Fan Shroud: Being an all metal hotend it is imperative to have active cooling on the heatsink.
The v6 sticks with the previous 30mm fan, but this time has a custom injection molded fan shroud. This makes for a much easier and cleaner install. Especially considering the hexagon does not come with a fan shroud. It also looks very nice in my opinion Nozzle: Arguably the most important improvement on the E3Dv6 is the new nozzle design.
Previously the nozzle had one transition, a 2mm drill to the final nozzle diameter, typically 4mm. This creates for a very hard transition from size. The v6 adds a second transition.Your question may be answered by sellers, manufacturers, or customers who purchased this item, who are all part of the Amazon community.
Please make sure that you are posting in the form of a question. Please enter a question. PT's are high temperature, high accuracy temperature sensors that you can now use on your E3D V6 HotEnd instead of a thermistor or thermocouple. E3D's PT sensors are also very easy to handle, being of a metal cartridge type construction that is secured with a set screw, no more fiberglass sleeving or clamping washer.
Please be aware that a PT is not the same as a thermistor and unless your electronics explicitly supports RTD Sensing devices you will need an amplifier board. The Ultimaker 2 uses PT sensors by default, and this sensor allows you to connect your E3D Hotend and Ultimaker electronics with no alteration to the electronics or firmware of the Ultimaker 2.

This works well once assembled, but can be fiddly to assemble and maintain. From mid-June E3D Hotends will transition to using a standard cartridge-type format for temperature sensors. These will be available as Thermistor, PT or Thermocouple sensors. Cartridge-sensors are to be used with an updated design of heater-block, into which the sensor cartridge is secured using a grub screw.
The new cartridge-sensor heater-blocks are marginally larger than the previous clamping washer heater-blocks. Cartridge-sensors are much faster to assemble, easier to maintain, and quicker to change to different sensor types. The new sensor format is also more robust and tolerant to abuse. All E3D-v6 hotends will be supplied with the new style thermistor-cartridge, and the new heater-block into which these fit. PT and Thermocouple cartridges are also available as optional upgrades.
The 3mm diameter x 10mm length cartridge is fitted with a Molex Microfit 3. There is an accompanying mm cable with matching Molex connector supplied with each hotend. If in doubt opt for the thermistor sensor type. These are supported by almost every 3D printer electronics and firmware and are easy to use. Our thermistor cartridges are based around the Semitec GT2 thermistor which is capable of sensing up to C - plenty hot for almost every printing material on the market.
Thermistors can be directly connected to most electronics to the thermistor input. Details on how to configure your firmware to use this thermistor can be found within the v6 documentation. If you have a desire for high performance temperature sensing you may wish to use the PT Sensor cartridge. PT sensors are more accurate than thermistors and capable of sensing much higher temperatures - higher than the melting point of the aluminium block provided as standard.
Higher temperature heater blocks are available on request. PT sensors are not supported by most electronics by default and require a separate PT Amplifier Board to convert the signal from the PT sensor into an electrical signal your controller board can understand.
Thermocouples are for specific applications, electronics or setups that need a thermocouple. In general if you are looking for a higher performance sensor the PT is a better option. Thermocouple Cartridges are capable of reaching very high temperatures, more than hot enough to process any plastic.
Thermocouples are not supported by most electronics by default and require a separate Thermocouple Amplifier Board to convert the signal from the thermocouple into an electrical signal your controller board can understand.
E3D v6 Information, Installation Guides, and Review
Duet series electronics does not support analog thermocouple amplifiers, but supports digital thermocouple interface boards instead. See [  ]. The two sensors are extremely visually similar, however the PT sensor has longer lead wires between the cartridge and the connector.
In future batches PT sensor cartridges will be manufactured using red insulation on the lead wires, with thermistors continuing to be made with blue insulation.Construction health and safety quiz
Thermocouples are easily identified by their white with black stripe glass fibre braided lead wire and do not have a molex connector, but are instead supplied with a 1m long continuous lead, and fork terminals.
