You will have to try again with posting the pictures of the parts. Nothing saved.

It appears that JetCam is like a top of the range CNC machine without a cutting tool - You can do all sorts of wonderful things with it except produce a finished part.

I had a similar problem in the past which turned out to be noise spikes on the LPT parallel port. Not only was it causing random EStop's it was also causing false steps. I fitted a PCI parallel port card and this completely cured the problem.
Are you using screened cable (grounded at one end only) for your limit switches and EStop ?

btw. You are not a noob you are on equal ground to the rest of us - we are all still learning.

Hi Barry,

It is essential that you can reach the EStop at any moment. If the EStop is out of reach then by all means add another. Having one for each axis doesent really make sense as EStop is EStop no matter which one you press it will still stop the process.

Hi,

Two roller blinds, one mounted at each end of the axis with the ends attached to the table, sounds like an extremely good idea to me. Make sure you fit them the right way up so that stuff falls off the ends and does not get rolled up into the blind though.
