Work offsets?

Is there a place or way that sheet-cam can take a work offset - G55, G56 ,G57 etc and add it to the start of the code? I have one job so far the uses a fixture and my G55 offset, i used G55 as Mach3 defaults to G54 so i leave that one blank and use it for the general work. Ideally I would like all j...

Ah, thats a possible,

I will check that.

I used a 1.1mm rad in CAD but then requested a 2mm cutter plus 0.1mm finish allowance in CAM.

I guess I should have gone for a bigger radius?

When does sharpen corners not work??

I have a job with some small internal details that have three rounded corners and one sharp corner. The rounded corners have a 1.1mm radius applied and I'm using a 2mm cutter. When I check "Sharpen Corners" it's sharpening all the corners, is there a way to stop this? The angle threshold s...

Complicated add-on?

Hi Les, I had an idea that would be useful for those using SheetCam on a mill, or at least I can see a use for it. The ability to draw a selection box around a feature of a path and duplicate it onto a new layer so it can be pre-processed etc. as well as using the box or marquee as part of the path ...

I manually edited some code today to add a delay in the corners - it does not do what you expect ;)

The tail of the flame stayed where it was and did not straighten up like it was expected. The delay then just caused a divot groove where the flame stopped moving and at the angle it was at as well.

Would it not be better to pause for a very short time on the corner to allow the tail to catch up? You could do that using an 'on inside corners' path rule. Use a code snippet with code something like this: G04P0.2 I can't get that to work properly. If i have a snippet with G04 P0.3 in it, place th...

It might work, but what i think will happen is that while the tail catches up, the top will eat into the corner - you get a good base but spoil the top.

I will try it out though as soon as i can.

It also sounds a bit like going into "exact stop" mode on Mach3 which is generally not good.

Sharpen corners feature for plasma...

I recently cut a thick job on my plasma and it had lots of internal corners, these suffer as the plasma flame tail lags behind the nozzle which gives a sort of radius instead of a corner. I asked about and one way of giving a big improvement was to manually draw the cut path, run sheet cam with no o...

I think I have it, trial and error:) post.DefineVariable (xxxx Needed to be in the OnInit() function Then I just used a If-Then block to only allow the OnToolChange code to run if it has been skipped once already. One anomaly is that the code generated has the spindle speed in it twice but that will...

I've tried editing the post as i have done on my plasma but as soon as i touch it i get loads of errors? I place this at the start.. post.DefineVariable ("FirstTool",-1) My idea was to wrap the Toolchange event code in a If-Then block that says if FirstTool then do nothing but set first to...

Remove tool change code...

I'm using the standard Mach3 post processor and now have a semi-auto tool change routine built into Mach3. I need to remove the tool change command for the FIRST tool in a job as this is carried out before the code is loaded. Subsequent changes are fine. i.e. the Post needs to assume the correct too...
