Have you measured motor current during overload condition and normal? Perhaps a motor overload relay/breaker of appropriate rating would do the job. -- Ralph From: Dave Engvall Sent: Friday, June 6, 2025 11:50 AM To: Enhanced Machine Controller (EMC) Sub

I've been quite happy with Intel NUC's off ebay. The last two I bought were like this one: https://www.ebay.com/itm/176512633157 only I got 16GB ram in mine, for $76 and $87 each. -- Ralph From: John Dammeyer Sent: Monday, April 14, 2025 4:59 PM To: En

Sorry to hear that all your work over the years has gone out the door at auction, Todd, but I am interested to hear that retrofitted machines with LCNC controls have sold for non-pittance amounts of money. That is reassuring to me, since I am presently retrofitting a small VMC in my garage now, an

[Emc-users] minor Axis annoyance

2024-12-02 Thread Ralph Stirling via Emc-users
I've got a small suggestion for developers that work on AXIS gui. When you run linuxcnc without an ini file on the command line, it brings up a list of sims to choose from. If you select one, it asks you if you want to make a copy of it in your home directory. The allowed choices are "yes" or "ca

[Emc-users] direct drive lathe spindle

2024-11-03 Thread Ralph Stirling via Emc-users
I am toying with the idea of building a benchtop lathe around a Taig 5C headstock, with a direct drive motor. Frameless motor components are available relatively inexpensively now from AliExpress and some other suppliers, and could make a very clean, compact machine. The spindle tube on the Taig

Just be sure your field can't drop out without the armature shutting off. You don't want a runaway dc motor. -- Ralph On Sep 15, 2024 10:27 AM, Sam Sokolik wrote: CAUTION: This email originated from outside the Walla Walla University email system. So... Without ripping out the current spin

Re: [Emc-users] Carving a spiral

2024-04-10 Thread Ralph Stirling via Emc-users
Use the parametric equation of a spiral and compute it *inside* your g-code program. x(t) = c1 * t * cos(t) + x0 y(t) = c2 * t * sin(t) + y0 Choose as fine a step as you like for t and make a while loop to generate the x and y values and do G1 moves. See https://www.math.fsu.edu/~cstover/teachi
