Hi, finally i have some bits of machine working...yay !
but have had issues with x stepper, and had not yet tested extruder,
this morning i cross tested everything and realised that i CAN get X and E motor to work when NOT using extended cables
(to reach E motor i need double the length of supplied cable, for x i need about 1.1/2 times)
to join cables i stipped them back twisted together / solder and heat shrink
board- mega, ramps , DRV8825 stepper motor driver tuned to 0.6 volts
question is - perhaps i could reduce the length of X cable , redo joins, try to reduce the resistance (perhaps the lump of solder on join adds to this ?)
or get longer wires made up,
or try increasing voltage ( i think i tried to up it to 1+ volt and that didn't seem to make any difference, but i could try again)
ill try to test resistance, and measure length of cables
cheers
