Mach4 General Discussion / Success

« on: December 29, 2017, 06:37:56 PM »

Just thought I'd let all of those that helped me get going (especially Craig) that I completed my first cut of a Carbon Fiber drone frame.  Thanks all.

Mach4 General Discussion / Re: Setting to millimeters

We're not talking about a setting that hasn't already been saved and loaded due to a reboot, nor are we talking about the setting we are modifying getting out of sync with what is currently loaded.   The current config already has the units set to metric.  The metric setting has already been changed and mach4 rebooted.  Changing the motor Units/min speed should NEVER cause the jog rate to change from metric to inches.  The machine.ini file should contain the metric setting already.  Something is not paying attention to the units selection already loaded and stored and simply setting the jog rate to inches.  That is a bug.  If that doesn't convince you, then we will have to agree to disagree.

Mach4 Toolbox / CNC Edge Finder

« on: December 29, 2017, 01:15:36 AM »

Does anyone have a sample script for using a CNC Edge finder ( https://www.ebay.com/itm/253045917018 )?  I already have my touch plate code created for my M6 command.

Thanx,

Rob

How would you feel about it if Microsoft Word changed your printer settings after you specifically set something else? And then told you , you have to restart Word anytime you change a printer setting because some machine.ini has conflicting information and is being loaded at the wrong time causing unknown things to happen when you print?  I think you'd agree that was a bug.  Same difference here.  I do software development for a living and if I wrote code like that, I would starve.

I would call that a bug under any circumstances.  Software should never allow itself to get out of sync with requested settings like that.  It should detect the problem and force a restart or something of that nature.  They clearly understand the issue, they just need to take the time to fix it.

Allowing you to handle any updates to the config.

Hey Craig, correct me if I'm wrong, but since it looks like that board has a parallel port on it, couldn't he use a UC100 motion controller?  Might be a cheap way to get going. ( I did confirm you can connect to PC with parallel port).

You should be able to use this with your electronics as is with MACH4.

NEMA 23 Stepper - $25.21 * 4 = 100.84
M542T Stepper driver - $31.93 * 4 = $127.72
POKEYS57CNC  $159.22
Total: $387.78 + shipping/taxes

You'd also likely need a higher output power supply.  A 36v 600w power supply will be $80, or a 48v 1000w will be $150 so $500 would be bottom end decent for a hobby machine.

And to clarify, I don't have the CNC experience, but I do have a lot of experience with Stepper motors and drivers from building and using 3D printers for years, so I am comfortable recommending those parts.

Here is the box I built.   I have made room for a 4th axis.  It has a 600w 36v power supply.

I went pretty strong as I want to cut carbon fiber and aluminum mainly. 425oz/in stepers: https://www.omc-stepperonline.com/hybrid-stepper-motor/nema-23-bipolar-3nm-425ozin-42a-57x57x114mm-4-wires-cnc-stepper-motor-23hs45-4204s.html
and the M542 Stepper drivers: https://www.omc-stepperonline.com/hybrid-stepper-motor/nema-23-bipolar-3nm-425ozin-42a-57x57x114mm-4-wires-cnc-stepper-motor-23hs45-4204s.html

along with the POKEYS57CNC Motion Controller.

It is my intention to cut parts for a new  Z- and Y-axis for the frame.  I want a larger Z-Axis than the current 70mm and need it to be solid.
