Gcode on Circle, Arc and feed rate errors
« on: March 17, 2013, 06:14:18 PM »
I recently purchase licensed versions of Mach3 Version R3.043.066, and Newfangled Mill Wizard Version 1.03 and install them on my PC running Windows XP professional, and everything seem to be working fine with the exception of making up the Gcode in Newfangled Mill Wizard for Circles Arcs or Arc plunge and try to run it in Mach3.  I get an error code.
Zero radius arc, Block= G02 X-22.2250 I-22.2250 F100.0

The other problem I am having is the Feed Rate on some of the Programs cutting options for example the Rectangle function the plunge feed rate is the only one carried through the entire Gcode See code below

Ok, I found the problem- we set the feed to plunge rate before doing the ramp, then forgot to reset it to feed rate after ramp. This was both linear and helical ramps.

We will post an update soon.

I am going to Brians shop tomorrow, we will talk about a better way for me to update the installer. Right now I have to depend on Scott to do it.

Brian is having the web site re-worked, and he is  trying to find a way I can update just the wizard installer.

I have attached an exe file to this message. If you download it, unzip it and put the NFS-mill.exe file into the program files folder to replace the current one it ought to work.

If for some reason this fails, just re-run the release installer, it will put everything back.

Sorry I dont have a better way to do this yet. We will, but its going to be a couple weeks. I am leaving today for Cabin Fever and NAMES shows, not back until April 23. I will be following mail and this forum, but will not have access to the dev machine. Brian and the rest of the Mach crew will be leaving tomorrow for Cabin Fever.

Hi Ron,

Above not completed;  creating a code with the wizards (the old version) the feed rate is OK.; I am using version Mill Wizard ver 1.00;  what is the latest one ?

Thank you

The latest version on the web is 1.0.17 I think it has most of the feed rate fixes except for keyslot. That has been fixed in the code but that version is not on the net yet.

Hi Ron,

Tks for the feedback;  tried again and worked but need to uncheck the "Spiral Z step"  if checked feed-rate keeps low;  understood very soon will have a new release and hope all this is fixed.; correct ?

Thank you
