I have just received Cohesion3d board to replace existing M2 Nano Controller Board, on inspection of the stepper motor pins on the Nano Board, i see that the X axis header has no cable attached, i pealed back the protective wrapping and it looks like Y cable has been folded back (assumption on my part !) would have to do a bit of a de-construct to prove this…should i be worried about this and just plug in the Y axis only to the new Cohesion3D Board
Can I assume this means this is not a working unit? As in both the K40 and C3D are new?
Can you elaborate on this? I don’t understand what you mean by this or the implication.
You would need both for your laser to work with C3D unless I’m missing something.
I assume the X cable fell out during shipping, can you trace it back from the motor?
My 12month old K40 was working ok, until a month ago, then Whisperer stopped talking to the K40, i decided to get a Cohesion3d cont. board and LightBurn Software.---------Regarding the old M2Nano which was working, with only the Y lead connected, as shown in the previous pic… ---------About peel back protective covering, Picture attached should explain, will have to dis-assemble stuff in the cutting bay to discover the rest of the cable.
Looking at the board more carefully it looks like the ribbon cable might be used at least partially for the X-Motor.
This type of configuration is described in the C3D installation guide:
K40 with M2Nano Cohesion3D LaserBoard Installation Guide - Cohesion3D
Regarding my issue with the fold back of the Y stepper cable i was able to find that it was just the shortening of the cable.
I agree with u re the Y axis and Ribbon cable configuration mentioned in "Here is another possible wiring configuration of the K40. I refer to this one as the “Ribbon Cable + Screw Terminal Power Supply” Variant. So can i presume to connect ribbon and Y axis plug as shown in …
Thanks Trevor
