General Mach Discussion / MACH3 screen not able to go "full screen"
« on: April 04, 2010, 11:40:47 PM »
Hi guys,
I've been wondering why my mach3 is unable to go "full screen" on my monitor? When I press the "maximize" button from windows, the Mach3 screen stays the same size and creates a huge black border to its right and underneath to fill the screen instead of scaling up.... So basically my Mach3 screen does not want to scale up.... any thoughts? All other softwares scale up fine.
thanks
Max

Yes I am using steppers and they do not seem to skip when properly tuned...
you are talking about motor tuning and axis calibration.... aren't they the same? If i use axis calibration and tune the motor this way, I can no longer tune them manually otherwise I will mess up the calibration , right?

Thank you Rich,
So you are saying once you tune your axiis with "motor tuning" and then again with axiis calibration, the rapid is set and you are not able to adjust it after that?

General Mach Discussion / how to "set" rapid feedrate G0 in MACH3
« on: April 04, 2010, 04:56:15 PM »
Hello,
I have made a homemade 3-axis CNC mill and have been testing with Mach3 with good results.
I am wondering if the rapid feedrate can be set or adjusted in any way in Mach3?
The reason I am asking is because since I calibrated my axiis with the axis calibration function within Mach3, my feedrate went WAY WAY down to an unacceptable level. If I bring the feedrate back up with "motor tuning" then my calibration is WAY off... meaning if I ask the X axis to travel 1", it will do 7". So at this point, it's either I have my axis well calibrated but deal with an impossibly slow rapid or I have good rapid with axiis that are WAY off... Any thoughts?
Thank you in advance

Thank you guys.

The test program is:
%
G0 G17 G20 G40 G49 G80
G91 G28 Z0
T1M6
G0 G90 G54 X-0.5 YO S5500 M3
G43 H1 Z1.
Z.1
G1 X0 Z-.1 F10.
X0.5
G3 X0.5 I0.5 J0
G1 X0
X-0.5
G0 Z1.
G91 G28 Z0
M30

What is the best way to check for backlash?

Thanks

General Mach Discussion / machine produces OVALS instead of CIRCLES???
« on: March 25, 2010, 09:14:32 PM »
Hello all,
I recently finished my homemade CNC 3-axis mill and have been experimenting with Mach 3 with some success. However, when I program a circle or an arc with simple G2 or G3 code, the result is not round but rather ovalish in shape. I did the axis calibration for a second time but the results were similar... Does it mean, I am not calibrating the axis properly, or is there anything else in the configurations that could cause that?
thanks in advance
M.
