I suspect my X-axis driver is dying and want to remap it to use the E1 motor.

I tried this but now the X+10 moves X and Y and Y+10 does exactly the same

Any idea how to get rid of these ripples? Predator running a duet wifi complete with springs on rods and a Genuine Bondtech BMG. Belts nice and tight.

Thanks dc42, got it working in the end

M400; Wait for current moves to finish
M915 P3 S2 F0 R0; set stall detection threshold
M913 E90; reduce the motor current
M83; relative extrude
G1 S1 E500 F3000; fast extrude
M400; wait for current moves to finish
M913 E100; restore motor current
G1 E20 F300 ; extrude slowly 20mm of filament

@dragonn That could be the answer, thanks! It's a belt driven delta yes

Thanks dc42, that makes sense now

So, I run G32 followed by a G29. When I try to reload the height map on my next print using G29 S1 I get the following error

Warning: the height map was loaded when the current Z=0 datum was not determined probing. This may result in a height offset.

I read the docs but not sure how to reload the datum as my probe is detachable, so I cant use it when actually printing

@bondus Thanks, i'll certainly give that a try. Do you not suspect the rods at all?

Such a shame as otherwise it is a very well put together machine.

@dc42 If that was the case, would that indicate an issue with the belts or the toothed pulley?

Bit tricky to tell but they look around 4mm

Left is 0.4, right is 0.8 width. I had a brainwave and converted it from a flying extruder to a full bowden. Unfornately it didn't make a blind bit of notice

I would guess standard 1.5A

@dc42 I've tried all the 'magic' numbers, doesn't seem to make any difference

0.0809, 0.1618, or 0.3236
0.1294, 0.2589, 0.3883
0.2 even 0.2589

No idea what the rated current is, the motors have no markings on them

Some more examples
