hybrid setup for test: adding extra axis to delta
-
To test my new setup of duet delta i have to test it, so instead of disassembling working printer i decided to add extra motor with rail, endstop and belt. basically 1/3 of delta picture below.
extra motor is 0.9 degree (current ones are 1.8) and is connected to E0 and i have added it as a new U axis.General idea: to run new motor for 10-15 hrs and see temperature, noise and other things.
new axis is longer than current printer. so, the question:
how to change that U-axis length in config.g with delta printer ?
thank you in advance
U-axis add-on:
M569 P4 S1 ; for TEST of extra motor M584 X0 Y1 Z2 E3 U4 ; U4 for TEST of extra motor ...

I don't have an answer... just chiming in to say how amusing that 1/3 printer looks...
Great job!

found a solution
M208 S1 U-220 ; here we tell printer to "extend" U-axis below 0 up to -220 mm G1 F9000 ; set high speed G1 U190 ; go all the way UP G1 U-220 ; go down to -200 ... G1 U190 G1 U-220 ... ...
