@dingo007 Yupp thats resolved now... all motors working

@dingo007

so to update all.... i have a new cable and end stop on the way... and yet what do i find....

the simplest of mistakes by reversing black and white wires by the builder, I chase issues for 2 days.

Bingo... that worked, have GUI now Thanks

@fcwilt i have the proper omron cables being delivered tomorrow, no idea why they solder these ends.

@dingo007 and this is fixed now, XYZ all home correctly now,

thanks for the config hint

@dingo007

ok and this is compared to the machine home position X0Y0 including the probe offset ?? so im measuring from that point to the pivots i take it.

@fcwilt

ok here is the top and bottom side cad of the bed, plus the photos of it above, im literally not sure what/where to measure. Am I measuring at the screws, or the ball studs, which align under the board and offset slightly with a bracket, am i measuring at the screws, or the ball studs, also do i include the offset from the board to the ball stud? and you will also notice on the rear screw it has a mount from the Z rail with a ball screw, the board sits on it centered.

for M671 ... I tried the below thinking i would measure at the ball screws, yet when i run the G32 leveling the right and read go way out of whack.

; Screws
M671 X20:125:230 Y20:280:20 S4.5 ; leadscrews at rear left, front middle and rear right

and in bed.g
G30 P0 X20 Y20 Z-99999 ; probe near a ball stud
G30 P1 X125 Y280 Z-99999 ; probe near a ballstud

mmm think i nailed it now...

@dingo007

I removed the G29 And still thats whats giving me the error, so im not sure im measuring the probe points right. is it where the physical screws actually are? or where the ball mounts are under the board??

So Im pretty sure im not understanding the M671 Logic i read in that guide. Ive tried from the guide however

@dc42

great are those cordinate defined as where the lead screw physically is, or where it mounts to the bed, as there are ball screws under the hot bed, these are extended a bit inwards by the mount from the lead screws, basically we followed the HEVO triple Z axis design, tough its modified a bit.

Front Left

Center rear

However notice the screw is offset and the rear is actually mounted at the rail

ill look around for an example bed.g

@dingo007 and this is fixed now, XYZ all home correctly now,

thanks for the config hint

@dingo007

i have a 300x300 triple Z scew... and a BLTouch, no endstops on Z with a Duet3 board... think you can take a crack at it getting a config done for levelling

@fcwilt

ok whats your configuration look like, ill never accomplish this without help

@fcwilt

nice vid, im not using endstops on Z though, just the bltouch, still trying to figure out the whole configuration
