The reserved ones have great definitions built into Code Expert & the documentation, but there are a lot of variables that are used in most of the posts I've seen, that although used very often, are not reserved and therefore not documented. If I ever get the chance, I'm going to build myself a glossary of them.

Actually, this is the 1st time I've had this issue. So, hopefully not. Also, it looks like that snippet is for testing the junction between 2 different arcs not the issue I'm having. I could be wrong though, I am always struggling to interpret what the variables represent.

I would've thought that this section would ensure there was no mismatch. #Check for mismatched arc data if xyarc, [ arcrad1 = sqrt((fmtrnd(xcabs)-prv_xabs)^2+(fmtrnd(ycabs)-prv_yabs)^2) arcrad2 = sqrt((fmtrnd(xcabs)-xabs)^2+(fmtrnd(ycabs)-yabs)^2) ] if yzarc = 1, [ arcrad1 = sqrt((fmtrnd(ycabs)-prv_yabs)^2+(fmtrnd(zcabs)-prv_zabs)^2) arcrad2 = sqrt((fmtrnd(ycabs)-yabs)^2+(fmtrnd(zcabs)-zabs)^2) ] if xzarc, [ arcrad1 = sqrt((fmtrnd(xcabs)-prv_xabs)^2+(fmtrnd(zcabs)-prv_zabs)^2) arcrad2 = sqrt((fmtrnd(xcabs)-xabs)^2+(fmtrnd(zcabs)-zabs)^2) ] if fmtrnd(arcrad1) <> fmtrnd(arcrad2), [ #if arcwarnflg = 0, result = mprint(sarcwarn) #spaces$ = 0 #pn, pspc, sm00, " ", scomm_str, sarcwarn, scomm_end, pe #spaces$ = sav_spc #arcwarnflg = 1 #result = fexist(snircmd) #sparams = 'speak text "' + sarcwarn + '"' #if result, result = launch(snircmd,sparams) ] if hel_lead = 1, pcirout2 else, pcirout1

It still outputs a different end point than the start point though. G1 Z.9476 F25. G41 D17 X-4.2967 Y4.0874 F8.25 G3 X-3.6192 Y3.739 I.3388 J-.1742 X-4.2968 Y4.0874 I-.3388 J.1742 G1 G40 X-4.1189 Y3.9959

@JParis, I'm a dumba$$, I forgot to uncheck the "Allow 360 degrees arcs" box. I've already hand edited the original code, so we can get the parts out, but it looks like this might work.

Here is a zip2go of just the arcs. It's a Postability post, about 4 or 5 years old, but we opted not to pay maintenance. for CC.ZIP

Contuor

Apparently, I would have to modify the post for this, changing it in the CD had absolutely no effect on the output.

Do you mean the "Adjust start/end of contour"? If so, then no I do not.

Whoa! Allowing break arcs at 180° changed to output to cut in a completely different location, I shifted the work offset up & sure enough, it would have cut the hole in the wrong location. G1 Z.8349 F25. G41 D17 X-4.4971 Y4.0399 F8.25 G3 X-4.4971 Y4.0399 I.3388 J-.1742 G1 G40 X-4.3192 Y3.9484

MC is outputting this for an arc: G1 Z.9476 F25. G41 D17 X-4.2967 Y4.0874 F8.25 G3 X-4.2968 Y4.0874 I.3388 J-.1742 G1 G40 X-4.1189 Y3.9959 The result being that the machine cuts the lead in & lead out only, no arc. Anyone know is this an MC issue, or a post issue?

Opti-rough, in Model Geometry leave stock on the walls and none on the floors.

I didn't realize there was an Update 3 issued. Is there a document that says what the changes are? I t didn't say with the "Info" button on the downloads page.

Wondering if this can be done in design
