My pleasure sir.

You should perhaps consider adding the G90.1 or G91.1 (as appropriate) to the start of your Gcode programs so that Mach3 doesn't get confused again in the future.

General Mach Discussion / Re: Mach3 Z Axis Travel Not Complete for Next Instruction.

« on: July 16, 2016, 02:07:08 AM »

Just some rambling’s…

I don’t think there is any defined method for establishing Velocity and Acceleration other than by ‘trial and error’ where they are each individually increased until the point of stall then reduced by 30 %.
If your machine is going to be used for substantially different tasks (eg. Wood routing / pcb engraving / etc.) then it makes sense to create and use different profiles with each, individually set to optimum performance (Velocity / Acceleration / etc.) for the intended task.
I am not aware of any means of setting Exact Stop mode just for the Z axis movements. You could, of course, use G61 / G64 before and after each Z axis line of Gcode but that would also slow down overall program execution speed. You could also perhaps consider modifying your post processor to add a G4 dwell (P #) following each negative Z movement, the delay being great enough to allow complete axis travel.
Another option and one that I would do, is to reduce the clearance Z height above the pcb. Assuming everything is flat then 1mm clearance would be more than adequate.

Assuming your Z axis down movement is on it's own line of Gcode then changing the Motion Mode to Exact Stop (Config. / General Config.) will cure the problem but it may slow down the overall execution of the complete run.
Another possible solution would be to increase Acceleration (perhaps reducing Velocity if necessary) for all axes (not just Z axes).

Ahh, the dreaded crop circles...

Config. / General Config.  change the IJ Mode (approx. centre of page).

It may depend on your new screenset but…

Pressing the TAB key brings up the MPG window the Slow Jog Rate determines the Arrow key % jog rate and this is then overridden to 100% jog rate by the Shift + Arrow keys. If your screenset does not work this way then check out the screenset for the problem.

Thanks for explaining it all Rich.

As said, I really didn’t know just why I have this obsession but it is all starting to make sense now.

My wife says that "all men should be put onto ‘Prozac’ (Fluoxetine) from the time they come off Mother’s milk" – perhaps this is where I went wrong.

I don’t know why but I seem to have developed an obsession with Jukeboxes (a second childhood perhaps ?). I already have a 100 selection vinyl, a 2000+ selection CD and a 10,000+ selection all electronic type but I just can’t help myself and have started to build yet another.
This one will be housed in a wall-hanging cabinet constructed of 18mm and 22mm birch ply and before it is all finally glued together I have started CNC routing all the various cut-outs. The front door (housing a touch screen) opens on three concealed cabinet hinges and it took a couple of practice runs to get the hinge positional cut-outs just right. It will contain a small 3+1 amplifier and speakers but will also have an output to a power amp (if required). I have just completed some of the speaker grills which were cut from aluminium faced traffolyte (engraving laminate) and thought I should post a couple of pictures as the project progressed.

I notice you are using an old version of the ESS plugin. It may be worth heading over to the Warp9 site to download their latest version and also check that you are running the recommended version of Mach4.
Perhaps download and run their latest SCU – I have found that it makes the setting-up just so easy.
