@dc42 Finally figured it out. I must of had too many adult beverages when I wrote the previous post.

I used M206 X-15 Y-15 Z-11.20 in my homing files and now everything works great. I tried G92 but that didn't seem to work for me.

I finally got the endstops and motors working on my Davinci Pro 1.0 conversion. However, the machine frame is designed, such that, if you try and home the y axis it crashes into the sheetmetal if the tool head docked all the way to the right. Short of moving the endstop how can I add 10 mm to the origin as calculated during homing.

I tried use M206 Y10 but on the web page under machine status is now lists the head position as 0, 10, 0.

I also tired M208 X10 Y10 Z10 S1 didn't work either.

My question, Once I home all 3 axis, how do I move the head to this new position and make it the machine 0?

Thanks @T3P3Tony

I set the thermistor to M305 P0 T400000 B3950 C0 R4700
and now it reads 21.5 C. Measure the bed with Infrared Thermometer and that reads 21.8 C. All is right with the world.

I wish XYZPrinting listed more info about the components in their printers.

Hello looking for help with the bed thermistor of the Davinci Pro and Duet3d WiFi. The temp is reading 2000 C. I have traced all the wires and tested VSSA fuse.

VSSA to Ground = < 5 Ohm
Resistance of thermistor = 430 kOhm at 20 C

Here is my config.g
; Heaters
M305 P0 T100000 B3950 C0 R4700 ; Set thermistor + ADC parameters for heater 0
M143 H0 S120 ; Set temperature limit for heater 0 to 120C
M305 P1 T100000 B4388 C0 R4700 ; Set thermistor + ADC parameters for heater 1
M143 H1 S280 ; Set temperature limit for heater 1 to 280C

What am I missing?

Thanks.
