Issue with Y-axis speed and extruder 0.92.9 DELTA RADDS 1.5 RAPS128 DUE

printjob

Hi all,

I recently upgraded my Delta printer to RADDS 1.5, RAPS128 and Arduino DUE to improve movement and print quality.

My issue is, that the Y-axis is much faster than X- and Z-axis. Also the extruder (E1 on RADDS) doesn't work.

I got 0.9?? stepper motors for all drive axis (X,Y,Z) and 1.8?? for extruder (E1). Radds board is configured at 128 steps for drive and 32 steps for extruder. RAPS128 are at 1.92V and decay at default.

I tried to switch RAPS on the board but the problem persists at Y-axis.

I also tried 0.92.8 and 0.91, problem is still present. M502 and M500 didn't help either.

I think the hardware is working fine and reckon it's a wrong setting in the firmware.

I can't figure out any solution, so any help is highly appreciated!

Deltas have only one steps per mm and that is z. I think your jumper for y are not set correctly or the contact is not set also it seems they have same position. Measure the ms1-3 pins on driver socket to compare.

E1 could be anything. Extruder not hot (Try M302 S1 to allow cold extrusion), driver inserted 180° wrong, check extruder stepper settings for 0/NaN values.

set STEPPER_HIGH_DELAY 0 for RAPS, no need to waste time with these.

Hi Repetier,

thanks for your fast reply! Your suggestion to measure the ms pins led to MS2 of Y-axis has no connection, so it was set to 1/32 stepping :( . Is there any way to fix the dipswitch, before I solder a cable between the pins of MS2? Or I'll just try to get a replacement.

Driver is twisted 180° to the axis drivers. Will give M302 S1 a try.

Repetier

Yeah, Ex drivers are 180° rotated to xyz drivers, some forget.

Simple solution would be to switch y and E0 (E1 on board). In config tool you can select socket to use. So use Y socket wich has 1/32 steps for extruder where you wanted this anyway. Then you can use E0 for y axis with 1/128 setting.

Soldered a cable between the pins of MS2 (Y-axis) and everything works fine now!

The lost connection might have affected the extruder too, now it also works.

Thanks again :)
