General Mach Discussion / C11 BOB controlling a huanyang 2.2kw inverter - no RPM display

« on: December 29, 2014, 07:03:20 PM »

I am having trouble getting the C11 BOB, Huanyang 2.2kw inverter and spindle to communicate with Mach 3 screen (RPM).  I can turn the spindle on and off and can control the speed with the inverter but it will not display the rpm of the spindle in mach.  If you touch the + or - buttons for spindle speed in Mach  it will display rpm for a brief moment ( the length of time the button is depressed)  Can anyone help?

Yes, I do .  What I am trying to do is to put an active low signal on input #1 (or any other input that will work) which will lock out the spindle relay connected to output #1

General Mach Discussion / Additional Spindle control

« on: December 15, 2014, 01:13:57 PM »

I have set up my spindle control in mach 3 and I can turn it on and off by pushing the spindle button on the Mach 3 screen.  I would also like to add another safety control to the spindle via a selector switch connected to a input.  This switch would lock out the spindle control.  I have assigned it to an input but don't know how to program it to disable the spindle output.  Can anyone help me out?

General Mach Discussion / Soft limit and homing Problem

« on: December 09, 2014, 08:57:42 AM »

I am having a problem with Homing.  When the machine hits the homing limits it will not back off the limits.  If I hit the reference home button it homes again and moves closer to the table limits.  It appears that it is backing off in the wrong direction.  Nay suggestions

General Mach Discussion / Slaving an axis trouble

« on: December 03, 2014, 07:24:32 PM »

 I  am having trouble slaving the x-axis to the a-axis.  Went to config/slave axis/x-axis and checked the slaved a-axis slot.  restarted the program and it will not slave.  in fact i tried every combination and nothing (Slaved x to a, y to a z to a).  I did notice that the Zero4 - DRO does not move when the axis was programed to slave .  when i do not slave the a-axis the dRO moves and so does the motor.  So the motor and driver are good.  Yes i have one of those chinese XHC-MK6 motion controllers that stipulate that it is Mach 3 capatiable.  Any suggestions, does anyone know where i can get support from the XHC-Mk6 motion controller?

General Mach Discussion / Slaving x and A axis issues

« on: November 25, 2014, 08:44:07 AM »

I have a large DIY CNC router (5' x 10')  and want to slave X and A axis.  I have two questions?   (1) Do I have to have two homing switches for the X and A  or can I use one.  I don't want to rack my gantry.  Spent three days getting the linear bearings parallel within .001 over 10 feet. .   (2) The X axis is a rack and pinion so one motor will turn clockwise and the other counter clock.  How do I program this in Mach 3.

I am a little confused.  When you say connect them to the 5V do you mean the +5V on the power supply and to pin 2 on the breakout board then change the change the pin 2 in mach 3 to active low? .  Also what is TTL?
