Hopefully I am posting in the right section. I have an issue that could be related to a couple of things but I have gambled on this...
I have just converted my home-brew printer from a Cartesian to corexy and made a couple of other mods too. I was originally running DRV8825 stepper drivers, which I've changed to BTT TMC2209 V1.2's (with UART) and with it, upgraded to Marlin 2.
Having completed re-assembly and Marlin config, I am pretty sure that my motors are not being supplied with power. After powering up I've completed a number of troubleshooting routes, which includes buzzing out motor wires to make sure they are all working correctly and the stepper drivers are connected to correct lines in the motor. I have also confirmed that each driver is receiving 12v and the VCCIO reads 5V and both the 12V and 5V board outputs are reading their associated voltages. Both the heated bed and hotend power up and achieve desired temps. I think this rules out a dead board. I have also tested a spare 2209, which also results in no power output. The drivers are read by the board, so an M122 command gives all relevant driver info. My final test has been to replace my E0 TMC2209 with an original DRV8825 (updating Marlin accordingly). This results in motor movement, which i think means there is connection between drivers and motors (not shorted something there).
Back to 2209s. I have been puzzling over this for a week now and I have no idea what the issue could be. This is my first stab at configuring using both Marlin 2 and TMC drivers so there is a chance I have missed something obvious but after comparing my build to several tutorials, I can't see what I have done wrong. Any help would be HUGELY appreciated!
Full build is as follows (wiring pictured, also):
Board: Makerbase MKS Gen V1.4 (MS1, MS2 & MS3 jumpers disconnected beneath stepper drivers)
PSU: 12V, 30A
Drivers: BigTreeTech TMC2209 V1.2
Motors: MT-1703HS168A
Endstops: Physical (to rule out a potentially oversensitive stallguard)
FW: Latest Marlin 2 (as of 05/07/2020)
Thanks in advance,
DK
