Railcore motor's moving at different speeds.
-
Just like the title says. I have a CoreXY printer I just got set up, specifically the Railcore ZLT. It uses a Duet 2 and a Duex 5 to control the 3 z stage motors (connected to the Duex) and the rest(connected on the Duet). The problem I am running into is the 3 motors for the Z stage don't move the same distance, and the two motors running the XY stage are also out of sync.
On the Z stage one of the motors out of the 3 is moving about half the speed as the other two. They sound fine, no odd noises coming from them. The same thing seems to be happening in the XY gantry as well, when you jog one direction, the print head moves kind of diagonally as one motor isn't spinning as fast as the other.
I am using the standard config file supplied from the railcore guys. All the motors are the 0.9 degree LDO motors from the railcore kit.; Communication and general M111 S0 ; Debug off M550 PRailCore ; Machine name and Netbios name (can be anything you like) ;M551 Pmyrap ; Machine password (used for FTP) ;*** If you have more than one Duet on your network, they must all have different MAC addresses, so change the last digits M540 P0xBE:0xEF:0xDE:0xAD:0xFE:0xEE ; MAC Address ;*** Wifi Networking M552 S1 ; Enable WiFi M555 P2 ; Set output to look like Marlin M575 P1 B57600 S1 ; Comms parameters for PanelDue G21 ; Work in millimetres G90 ; Send absolute coordinates...

If you swap the motor that is misbehaving to a different port does the problem stick with the motor or the driver?

@phaedrux That's the next step in the morning, it almost seems like the 0.9 steppers are labeled wrong or something
