Bryce, I would (and did) avoid using Gantrykins. It is rife with bugs (like ignoring MAX_VELOCITY, or try jogging with keyboard keys in Manual Tab/World Mode and over 488ipm - gives immediate fault but in Joint Mode/Manual Tab, can jog at any speed) and/or gotchas (World Mode only supports con

[Emc-users] simple conversational utility to cut off remnants

Is there a simple conversational way in Linuxcnc (2.5) to cut a straight line or a simple pattern? After cutting some parts on a large sheet with the plasma machine today we wanted to cut a straight line starting from a touch off point at a specific feed rate ending at a specific distance. Thi

[Emc-users] Glade, reload/load file objects not working?

We have "Touch Off All" as well as "Touch Off X", Y and Z buttons in our Glade panel for the plasma table. After touching off, if the file is already loaded you have to reload the file for it to appear at the new coordinates. Axis does this by default when you use it's touch off commands. So

Re: [Emc-users] More control board questions

On our current machine (the gantry plasma machine) we are using 7i42 buffer cards with a 7i43 card and a custom firmware load from Mesa which has 4 step/dir and 4 single ended encoder inputs. We built a small board that converts the differential signals from our encoders to single-ended inside

I see that there an MDI command widget in Glade. We were just complaining that it is a shame that Axis has a manual tab and an MDI tab that are separate. If I want to be able to jog in MDI mode, why not? There should be one screen to control everything. Anyway, I went to Gladevcp and found t
