If you can settle for silicone, Keenovo will custom make you one.


You can also get custom silicone heaters from Shenzen Ali Brother Technology via Alibaba. I paid about $35 for mine.

Re: How-to: Thermistor calibration

My advice to anyone wanting an accurate temperature reading is to use a PT100 sensor, not a thermistor. No calibration is needed, although most current electronics boards do need an adapter of some sort.

Re: Thermistor ADC H&L Values on Duet

I suggest you start by upgrading to firmware 1.17e. Next, if your M305 command for the hot end is not using a C parameter, use the configtool at reprapfirmware.org to find the ideal B and C parameters for your thermistor, or for E3D hot ends use the values on their wiki. The H and L parameters are i...

Re: Duet HE280 Probe i2c interface

Re: Auto Calibration points

I presume you are using my IR sensor then. 2.88mm may be within tolerance depending on how high the bottom edge of the sensor board is above the nozzle, and the bed surface you are using.

If anyone tries to open-source on of these beds, I'd be glad to help with the kinematics! If you write the slicer, I'll write the firmware! As 626pilot says, one of the main issues ...

Re: Duet AutoBed Compensation issue

You may find it useful to use the tool at reprapfirmware.org to generate the configuration, homing and bed probing files. But increase the dive height temporarily before you run auto calibration for the first time.

Re: Duet AutoBed Compensation issue

Do you really mean bed compensation, or do you mean auto calibration as I suspect? If it's auto calibration, see https://duet3d.com/wiki/Calibrating_a_d ... parameters and the following sections on that page.

... The Hackaday post says they haven't gotten the print head to move at the same time as the bed, so they aren't doing true multi-axis printing. Not that it isn't still extremely impressive, but from everything I've learned from CNC machining is that the hardware for multi-axis setups is easy, the...

Re: Delta Build

Was the cube 12mm in all of X, Y and Z? If so, that points to a steps/mm errors, although 80 sounds right for that configuration. If the Z height was 20mm and only X or Y were 12mm, that is an issue with diagonal rod length setting or calibration.

Re: Auto Calibration points

Will changing the outer probe points mess up the calibration? What I'm running into is that outer Y probe point is too close to the tower and the white tension piece is getting forced up against the hot end fan enough to stop the fan. I was hoping that moving the points in a little wouldn't complet...

Re: z axis homeing

If you are using NC microswitches or other endstop switches that produce an active high output, then it's normal for them to read stopped when they are disconnected. All other common firmwares work this way too. If the Z endstop led is not lit when your NC microswitch is not triggered, then you have...

Re: Duet w/Accelerometer Probe Warning

If the VSSA fuse failed then you had a short between one of the thermistor wires and something else. The most common cause is probably a combination of a short in the heater cartridge between the element and the casing (which puts 12V or 24V on the hot end metalwork) and a short between a hot end th...

I had a similar setup working some time ago using the wr720n nano router. I had to connect a laptop to it with an Ethernet cable to set it up. AFAIR I configured it in client mode with auto DHCP. I configured the Duet to use DHCP.
