Hello,

I am using a new controller board that uses pin 16 to enable (enable 1) the steppers for axis control and pin 17 to run a relay (output 1)for the spindle. The problem is they seem to affect...

Hi Gerry,

Thanks for helping. They just stop, but are still energized. They work using the on-screen jog with the TAB key. There is no noise or disruption when using the keyboard.

Hello,

I have been using Mach3 with my small homemade engraving machine and many times when using the keyboard buttons to control the stepper motors it just stops working, yet if I press the TAB...

Hello,

I have many quality DC servo motors with attached optical encoders and was keen on using a microcontroller to control a 3-axis machine. Maybe using Mach3.

Is this there any chips that...

Hi All,

I managed to fix the MACH pulsing problems using utility software that stops the laptop from slowing the pulse engine. It is an IBM X31 and I have had no problems runnning my home made...

Hi Switcher,

I have attached a sample of of code. The full code is over 26000 lines so I cut it down to two pages. The feed rate only ever shows the X-Y rate.

Hi mcphill,

Thanks for your help. I am using pcb-gcode. and I have set different feed rates for X-Y and Z, but like I said it isn't coming up in the final code. I also notice the drill G-codes...

Thanks Gerry,

I am using Eagle to make PCB's and the G-code converter for that allows separate X-Y and Z feed rates, but it does not seem to apply them to the z-axis ie. the feed rate is placed...

Hi All,

I have a small engraver and need to have a slower feed rate on the z-axis as compared to the X and Y. I'm using a fine tip cutter on circuit baords and the tip is breaking off due to the...

Hi,

I have setup a 1.6GHz thinkpad with XP Pro, to use with my 3-axis engraver. Using Mach3 it's been going fine and still works but when homing there has been a regular interuption in the...

Thanks,

Wont Mach3 home the same even if all switches are tied together and you select home as well as limits for the switches in the homing/limit settings ?.

Hello All,

I have setup my 3 axis machine with separate limit switches for each axis. So I'm using 3 inputs on the printer port. Is there any advantage having them separate ?. I am thinking of...

Hi Gerry,

Zeroing the z-axis to the bottom switch would seem the way to go, but when I have a tool in the spindle it will hit the machine table before the bottom limit switch !. My problem is...

Hi All,

Is it possible to set the decimal places in Mach's DRO's. I wish to limit the resolution to show to two decimal places as 1/100th of a millimeter is more than enough resolution.

Hello,

I have made my own 3-axis engraving machine from scratch and have everything running well, but I need help with the Z-axis setup. I have only used the ports/pins and the homing/limits to...
