Re: Pronest for Ethercut

Last time I talked to the Pronest and SigmaNest programmers the LT versions did not support embedded user variables so you have no way to do the automatic cut parameters (DTHC parameters ) and have them embedded in the G-code. Perhaps you have been able to get them to make the changes and do full to...

Re: Help with DTHC

MP1000THC is a bare bones POST and does not do anything automatically . THC on off should not be done with a macro (M code) with the DTHCII. I submit you will get better help on the DTHC and how to use it and what POST to use on the CandCNC Support Forum. It the Z is moving up during a cut the DTHC ...

Re: Corel Draw X8 SVG Export to Sheetcam

If the contours look correct in SheetCAM then the problem is not in the drawing. (beziers are not exported in DXF or SVG ) a pure arc is described as two end points with a radius, A Bezier is a mathematical description of multiple arcs with multiple radii joined as a poly object. Similar to a DXF sp...

Re: Tips for spotting looped lines/artifacts in drawings?

Only way I know is to take the drawing and if it has a bunch of objects (closed node chains) group them in smaller groups on different layers and see which lavers have the error. the layer that is a problem will still have to be looked at line by line....it just breaks the number of lines down .

Re: Baileigh PT44 retrofit torch height control

The Promo and most other after market THC's need control software like MACH that has the logic built in to take UP Down signals and move the Z motor. Even if you had available inputs in that controller they would not do anything . You choices are: 1. Find a stand alone THC that is self contained and...

Re: How to fix rounded inside corners

The problem with doing CV tuning is its global for everything you cut and it handles some shapes better than others. One setting is not optimal for all cuts. One of the compelling arguments for LINUXCNC is its better trajectory planner and CV method. Unlike the old one that MACH is based on, it does...

Re: Soft pierce peck, delayed off until after first cut.

cut amps are set in the DTHC ON/OFF sequence as "S1#" or S2#) S1 turns OFF the DTHC and Sets the amps to 10 times the # value in percnet. S10 is OFF with AMPS at 100%. S15 would be OFF at 50% . S20 is on at 100%. You have the global DTHC off on the cuts so it never issues any S codes in th...

Re: Delusional Designs CNC Support

That is not correct. The angled cut would present...

The 450 deal is for an upgrade from Ethercut Windows MACH with the DTHCIV. If you have the older Parallel port or DTHCII system you need to do the hardware replacement for 1100.00.
You might contact Arclight. They are going to offer an upgrade path as well.
