General Mach Discussion / Slow Jog % DRO
« on: March 11, 2016, 10:22:26 PM »
Is there any way have some code that rights a value to the Slow Jog % DRO? I have an up and down button that incrementally sets the value...would like a single button set it to , lets say 90%...another button set it to 5%...

Thanks in Advance

General Mach Discussion / Steps per inch
« on: March 11, 2016, 04:42:45 PM »
Please don't yell at me!  ;D ;D

I have looked at 30 or more posts on steps per inch, just when I think I've got , I am confused again!

1.8deg motors is 200 steps/rev...microstepping makes this 2000 steps/rev.

3mm belt and 20t pulley = .11811 inches (3mm) per tooth * 20 teeth = 2.362inches/rev

2000 microsteps / 2.362 = 846.74 pulses/inch


Do I have it right..

Thanks...

Was playing around this morning, thought it would be useful to have Mach3 know what tool I am using even when there is no M6 in the file (single tool for the entire job)...played around with some things which did not work, then did some research on here and came up with the idea of duplicating the M6 start (gets the current tool number) and calling it M500.m1s...wasnt sure if it would work, but it did! First line in the GCode is M500 T1, which updates the Mach screen with current tool is tool 1. I have my tools in VCarve the same as Mach 3, so this worked pretty good.

Once I got it working, I was wondering if it was useful or not...What if the tool in the router was the wrong one! This doesnt help as it would merrily continue with the cut!...maybe more useful is to get the VCarve processor to put an M6 command in when there is only a single tool in the file....hmmmmm...making Mach3 do what you wnat is almost as much fun as making things with the router!

General Mach Discussion / Movement after tool change
« on: February 13, 2016, 12:26:06 PM »
In my workflow (simulated of course! Still using TinyG), when I get a tool change, sometimes I jog the XY a little to do the touch off with the new tool. After I cycle start again, it moves back to where it was before the tool change, then back to the next position...is there a way I can write some code to eliminate it going back to where it was, and after cycle start, go to the next position?

Seems like I should be able to grab the XY for the next line?!? Dont know how buffering and other things might effect this...maybe something simple?!? Don't know!

Thanks

General Mach Discussion / External Buttons
« on: January 31, 2016, 10:16:23 AM »
Looking to add a few external buttons to Mach3...what are some simple options? Second parallel? Serial cable?

They way I am working now, I only need three buttons, Touch Off Z, Cycle, and Stop. Of course once I have these I would want more! Like maybe jog buttons! Looking to get started simply at first...I dont think I need a full pendant, and I can also use the XBox controller...still would like a small physical panel with three or four buttons to get me started....

Advice/opinions are greatly appreciated

VB and the development of wizards / Doing something wrong
« on: January 25, 2016, 11:21:17 PM »
I have the following attached to a button...code seems like it should work, i created two dros, OEM1300 and OEM1302, get a data type mismatch. When I step thru with the debugger, I am getting the correct values into XPos and YPos...can't figure what I am doing wrong..

Sub Main
   XPos=GetOEMDRO(1300)
   YPos=GetOEMDRO(1302)

      Code "G0 X" + XPos + "Y" + YPos
 

End Sub

VB and the development of wizards / VB Script triggered by Gcode?
« on: January 25, 2016, 05:51:40 PM »
Looking around in here and a lot of posts have to do with automatic tool changing...I do not have this but it got me thinking...can you make a script run when the Gcode gives certain commands, like M6 (tool change)? May be old hat to you guys, but it would be cool on my Ox style CNC router to move to the front of the machine (couple of user DRO positions), and wait for me to change the tool, press a button, move to the next location in the cut, touch off the Z axis, then take off. That would be way cool! I was just looking at my Gcode and I do not see a command to turn of the spindle when the M6 command comes up, but Mach3 turns it off so there must be some "hook" to know that a tool change needs to occur...if there are previous posts that explain this point them out and I will read them...

Thanks

Mach Screens / My screen
« on: January 23, 2016, 04:30:13 PM »
Been playing with MachScreen, learned a lot by looking at others screens and getting good answers on the forums...This screen matches the way I work my router...I am pretty impressed with it...Like the 2010 screen set, I like the wndows look...I have not used it for real yet, but I have run many simulations, tool changes, touch probing the Z, etc...I like it!

General Mach Discussion / Offsets strange behaviour
« on: January 23, 2016, 02:34:40 PM »
I have G55 offsets set to X+2.000 and Y+2.000...when I select G55, the DROs show -2 on X and Y as expected...if I then go to zero (G0 Y0X0) it moves to .0061 on both axis, and when I check the machine position, it shows 1.9939...I am not currently hooked to any drives, is this a function of the motor settings? Like it cant decel in time? Seems strangwe to me...

Thanks

Mach Screens / Redraw toolpath
« on: January 23, 2016, 02:26:53 PM »
I hope you guys dont get pi$$ed at all of the questions, I try to search the forums and figure it out myself before I ask!  ::)

I added a button to show or hide the table boundarys, I wanted it to regen after, used the do button 160 code (same code the regen button does),
cant get it to work...

value = GetParam("Boundry")
if  value = 1 then
  SetParam "Boundry" , 0
Else
SetParam "Boundry" , 1
End If
dobutton(160)
