Automatic band saw marvel v10a

Category: CNC Machines

Wouldn't be to bad to use linuxcnc. I'm in the process of building an automated saw with a magazine to load bars.

How does the bar feed work?
How does the saw feed work?

That's would determine my approach

Inverting jogging sense of X Axis on a VistaCNC P1A-S pendant

Category: HAL

Thanks Benb, I did that and unfortunately nothing changed. I guess what really determines the direction of the axes is halui.joint.N.[plus|minus]. I even took halui.axis.X.plus and minus out of the configuration line, and the pendant works with just halui.joint.0.[plus|minus].

In my tests I even commented out all the lines that have halui.joint.N.[plus|minus] and Velocity mode stops working, but to my surprise, Step mode still works. It is as if Step mode is set up somewhere else but I can't figure out where.

PlasmaC Voltage Divider

You can use a THCAD2 or THCAD-10 with a series resistor
or resistors, for example 2.4M will give a 250V full scale range.

Mesa has a set of three .4W 1M .1% resistors for this purpose, when used
with a THCAD-10 or a THCAD2 set for 10V you get:

1 = 110V full scale
2 in series 210V full scale
3 in series 310V full scale

Note that lower voltage ranges improve resolution so the 210 V range is fine for most
plasma systems as it will accept continuous inputs over 1000V without damage
and voltages over 200V are not typically useful when cutting.
