hybrid setup for test: adding extra axis to delta
c310 last edited by c310
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

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

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 ... ...
