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

Category: Plasmac

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.

Does the sim work? If so its a configuration problem.

Mesa Configuration Tool

Category: Configuration Tools

Hello guys! I've just noticed that I/O map for 7i95T from Mesa Configuration tool 2.1.7 is not complete.
The I/O map is missing connector TB5 and TB6 or am i just looking at it wrong?

Or is it because I'll have to configure inputs & outputs under the 7i95t tab to get pin names in my I/O.hal?
