Re: Thermistor Resting Value Incorrect

Even better, get a Duet WiFi/Duet Ethernet (OK, I am biased) with the PT100 daughter board AND a PT100 sensor, and use a 4-wire connection between the PT100 and the daughter board. See https://miscsolutions.wordpress.com/2016/06/25/more-delta-printer-upgrades-wifi-and-silence/. The use of a 4-wire c...

Re: Bondtech Extruder Occasional Clicking

I don't know the Bondtech extruder, but some extruders with metal gears tend to clunk when the extruder direction is reversed towards the end of a move due to pressure advance. Maybe it's caused by backlash in the gears. You could comment out the M572 command near the end of your config.g file to se...

Re: Massive retraction starting files back to back

You are probably using absolute extruder coordinates, and your slicer is not resetting the extruder position at the start of a file. Adding G92 E0 to your slicer start script may fix it. I don't understand why so many slicers default to using absolute extruder coordinates. Relative extruder coordina...

Re: Titan Extruder - Any changes to firmware/simplify

You will need to adjust the extruder steps/mm. If your firmware needs to be recompiled to adjust it, and you don't want to do that, then you should be able to set the correct steps/mm using the M92 command in your slicer start gcode script instead.

Re: How-to: Dimensional Accuracy Calibration for Delta Printers

Those using Duet electronics can use the M579 command to scale the axes, see https://duet3d.com/wiki/G-code#M579:_Sc ... esian_axes. But as it's already been pointed, geometrical errors on deltas generally have non-uniform results, so use this facility with caution.

With power off, swap your X and Y motor connectors, and your X and Y endstop switch connectors. Then recalibrate at least the X and Y endstop corrections.

Because 100 segments/sec is a commonly used setting in firmwares that use segmentation, and I was printing at 50mm/sec.

Re: Adventures in Noise Slaying

The TMC2100 and TMC2660 are very different drivers, although they share the ability to interpolate x16 microstep pulses to x256. In particular, the 2660s can handle about double the current, and they are highly programmable via SPI. I don't think any other driver can match the TMC2660 in 3D printer ...

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.

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...
