G91 ; relative positioning

G1 S1 X603 Y603 Z603 F1800 ; move all towers to the high end stopping at the endstops (first pass)
G1 X-5 Y-5 Z-5 F1800 S2 ; go down a few mm
G1 S1 X10 Y10 Z10 F360 ; move all towers up once more (second pass)
G1 Z-5 F6000 ; move down a few mm so that the nozzle can be centred
G90 ; absolute positioning
G1 X0 Y0 F6000 ; move X+Y to the centre

I dont have those files.

For my thermistors i use these
https://www.amazon.com/Anycubic-Thermistor-Wiring-Printer-Heatbed/dp/B01B41K7OM/ref=sr_1_3?keywords=anycubic+NTC+3950+100k&qid=1568564308&sr=8-3
For the B4138 should it be B3950?
Ill also switch back to 2.04rc and tune the parameters

Mine doesnt have a homeall.g file do you want the homedelta.g ???

Hello recently i updated the firmware on my duet maestro 1.0 to 2.03RC5 and when i home the printer sometimes it works and sometimes it doesn't. When it doesnt work it shows the error G0/G1: target position not reachable from current position and the only way to get it to home agin to to do and emergency stop and home it again. Also its a delta. Any idea what this problem is?
