An update.

The initial mounting method for the polarising filter suffered with a major drawback in so far as it allowed machining dust to enter and settle on top of the filter disc. I have replaced the two alloy spacers with a turned part that should resolve this problem.

Hi Jamie,

Sorry I just assumed you would know.
A breakout board (BOB) is where the LPT connection from the computer joins with the machine. Some BOB's are 'active' in so far as they incorporate opto isolators and are powered 5 Volts. The Gecko controller already incorporates opto isolators on its inputs and sometimes behaves oddly if active BOB's are used. For Gecko operation a passive BOB is usually used.
Hope this explains what I was getting at and once again sorry for posting a reply that was not fully explained.

Hi,
Two things to check:-
1) Are you saving the changes you make under the motor tuning menu ?.
2) Do you have 'constant velocity' checked in the general logic config page ?.
Answers to both the above should be yes.

It could be that the direction signals are somehow getting corrupted. You are not using and active BOB (with opto isolators) prior to your Gecko connection are you ?.

Hi all,

The current version of JetCam will not allow the .set screens file to be saved. 

Does anyone have a copy of the earlier version (which does allow the screens to be saved as a .set file) which they would be willing to share please ?. 

Thanks,

Tweakie.

Would be nice if the latest version would save the .set file like the old version did.

As Peter has said when the table moves to the left the cutting tool effectively moves to the right of the work, which is what the Mach screen is showing. It takes a bit of getting used to but think of the jog keys as moving the cutter on the work instead of watching the table movements.

Brilliant news about getting a replacement controller.

I doubt that this controller can handle the current necessary to satisfactorily run two motors wired in parallel. But it all depends on the torque required to drive the axis, maybe 1.25 Amps per motor will provide enough torque, maybe not. You would have to try it and see I suppose.
