Thc is not implemented on the ess yet.

Thc, or wait for arc Ok won't function

Update.... Warp9 have now today released a plugin via the forum (its a development plugin) that has probing working on one probe input

Mach4 has the potential for a number of probe inputs.... only one is working or can be set to function on the ESS.

You need to log onto the warp9 forum and download it from there.... not from the website as its a development release.

It is setup in the plugin, you need to go to the warp9 website and work through the information there, as basically all functionality comes through the plugin which means some of the stuff on the mach3 setup screens is redundant as it is only functional for the parallel ports

Stuff like backlash on the mach3 config screen, pulse width settings on the motor tuning page, and the check boxes for port1 and port2 on the ports and pins page have no effect.

Thanks Gary, I've reread your original post, again, and yup that makes sense now, (don't know why it didn't last time... think I shut off at cam, fix problem there....)

I'll give it a go,

Hood, oops, sorry got the wrong Scotland group, I was surprised how close that was (thought it would be out for sure), I hope this is more definitive or you end up neatly half not happy, but expect it'll be close (I've never guessed a vote right ever, so I don't think it'll happen this time), heyho, at least I've don't my bit with a tick in a box)

Thanks Hood as always

Hmmm, it's not really a "fix" that's required... it's a suggestion as to how would you realign a part you may have partially cut once, to finish it off later.

The precision of the holes that have been cut is not actually that critical, I was more curious about a suggested method (ie what would you do?)

Here is another more complex and precision scenario

I had a guy EDM cut an internal spline into an input gear of a transfer box, once completed it was test fitted and a bit too tight a fit.  He suggested that he would open the spline out and recut it again a little oversize.... problem was he was not sure how he would "pick up" the spline to recut it

~ 1 1/4" outside diameter, 31 teeth involute spline profile.  After some weeks of sitting on it, I asked if he wanted another blank to recut as it may be easier than attempting to "pick up" the existing spline and open it out a bit... he took me up on the new blank and recut.

Thanks Hood for replying,

I'll try to explain again (it may have been me trying on a phone).

Attached are two screenshots, basically the first one shows my original flange.

The second, my revised flange shows the original flange as an underlay,

The flange is to join a gearbox to a transfer case (4x4).

Hence I've decided to clock the transfer case.

I've cut a couple of the boltholes for the the flange (they are less important as they align via a spigot), and are for the gearbox.

Hence what I'm trying to do is to have a method to accurately pick up on these holes already cut and align their co-ordinates with the second attempt, and also allow for rotating the part co-ordinates slightly ( unfortunately the part export to DXF and my editing of the two objects to get their clocking means that when I created the new flange DXF, they unfortunately don't align as far as cad world co-ordinates and part rotation (I could rotate the 2nd flange in cad to align the first, but I was wondering if there was a method of picking up from on a previous part).

General Mach Discussion / M3 - pick up on a part for remachining

Hello

Is there a way to touch off and repickup on coordinates to remachine a part?

Let's say I have a square piece of stock, and my intended finished part (a flange) has a  number of holes in it, I have cut some of them, didn't finish the part,

I've since decided to rotate one set of mating bolt holes, re run the post processor (sheetcam), and now want to finish off my flange, how would I go about picking up the coordinates of the first set of holes, and rotating my machine coordinates to match those same bolt hole coordinates in the gcode.

Would I probe out the hole centres already machined then use trigonometry to work out the angle of my part, then probe out a hole and use that as my 0,0 coordinate, then rotate the machine coordinates accordingly?

Is there a routine or some other method.

Thanks for your time and any advice (besides start off with a new piece of stock...)

I'm sure Steve or Bob from PMDX will be by in a few hours to help guide you through it (us time zone, working hours)

Are you using Darwin (legacy parallel port driver) or a motion controller, if so which motion controller are you using?
