Re: TMC2130 Direct drive extruder issue - 7 years ago
I think I may have solved my problem. Linear advance k value was set. Apparently you can't have linear advance set and do a 100mm calibration extrusion without it missing steps. Lesson learned!by Krpepe - General
Re: TMC2130 Direct drive extruder issue - 7 years ago
imqqmi, Thank you for your reply! It appears I have missed some facts in my original post. The TMC2130 driver were purchased from filastruder. They are spi connected to the hardware spi pins. I am not using the software spi. I have adjusted from the stock marlin setting of .8ma in .1ma steps up to 1.1ma, no luck. You are correct that they do not use the jumpers under the driver.

Actual printer temps on hot end and bed - 7 years ago
Has anyone tested the actual temps with the firmware settings for the thermistors that are provided with the reprapguru i3? I did last night because I was having issues with prints. Hot end set at 210 C was actually 236.4, Bed set at 100 was 119. went into the firmware and the settings for the thermistors for both hot end and bed were 6. After a lot of testing, I found 1 works well for the hot enby Krpepe - Prusa i3 and variants
