General Mach Discussion / Mach3 Turn X axis problems

« on: January 01, 2021, 05:13:37 AM »

Happy New Year.
I have a home brewed slant bed late running with Mach3 Turn ver 066
Have an 8 tool ATC with tools set in the tool table according to the Mach3 Turn manual. Works perfect.
Running a program generated from Fusion 360 with post-prosesser Generic Mach3 Turning, first run works perfect.
Has removed G28 home but end program with G30.
Second run Z axis is ok but X axis in minus.

After running the program in air when completed
1st run Machine coordinates X-30.5, Z 0
1st run Program coordinates X+10,5 Z-22.57

2nd run MC X 0, Z 0
2nd run PC +71.53, Z-22,57

The same happen when running second run on a program generated from the Mach3 Turn wizard.

First run always perfect but second run always become a disaster.

I have checked end rechecked all setting but there are something wrong.

I have calculated the X to require 3,4 Nm with a SF of 1.5, which is direct driven by a tema 34 stepper motor with holding torque of 4,4 Nm. The X axis seems to work well, but it’s where the problem is.

Any suggestions?

General Mach Discussion / A axis will only run one way

« on: November 05, 2017, 12:10:57 PM »

I use the A stepper motor on my lathe ATC to turn the 8 tool turret.
Tool no 1 is set to 0, tool no 2 is set to 25.5 etc. Everything works well if i go from tool 1 to tool 2 until tool tool 8. Then problem starts when going back to tool 1, the turret continue the same direction, not in reverse. After the tools will not end up where it should.
It is Mach3 turn with paralell port. X and Z axis works well.
What have I done wrong?

General Mach Discussion / Tool setting changes Mach3 Turn

« on: October 04, 2017, 02:19:43 PM »

Hi
I have an issue. My cnc lathe has an 8 tool ACT. The tool table is set with tool no 1 as the master.
Normally every thing works perfect when canging tools but; i run the Mach 3 wizzard, save, post the code and run the code. Evrything is ok. Than I go back and do som changes in the wizzard , save, post code and than the tool setting is completly wrong. No toolchange has been done. Same tool in the DRO as well.
Than I restart the PC, set master tool and every thing is ok again.

General Mach Discussion / Mach3 turn

« on: March 26, 2017, 07:41:29 AM »

Hi
Anyone that can helpe me with this set of codes?
Im going to turn a collet that I draw in Fusion360 posted from there.
When I simulate it in Fusion360 COM it seems to be perfect but after a few cut the x axis just go into the steel and cut it right down with big blue chip.
I´m not sure which line it happen as I just hit the emergency stop.
I have run the CNC late with just simple G codes not generated G codes from fusion before.

General Mach Discussion / Homing

« on: March 22, 2017, 04:01:16 AM »

Hi
I'm working on job on the CNC router that will take about 8 hours. I have only a couple of hours available now and then.
I stop the machine and note down the line number, than put the machines three axis in 0 by G0 X0 Y0 Z0, shut off the PC and the control. When I start up again I just verify that the machines axis are all in 0 than load the program, find the correct line and hit Run From Here.
This works perfectly.

Normally when I start up I home the machine, then 0 the axis on the stock.

My question is; can I always just leave the machine in 0 (PC and control off) and start up again without homing just 0 the axis?

General Mach Discussion / Router stopped less than midways

« on: March 12, 2017, 08:59:30 AM »

Hi
I was cutting with my cnc router and Mach3 for about one houre than it stopped besause a limit witch triggered, non of the switches was triggerd. I belive the program is app 3000 lines and I had just over 1000 lines done.
This limit switch triggerd for no reason I know about, it has happend ones before. When I reset it seems to be ok.
I it possible to restart the process at line 1000? I shut the PC and control off but I know exactly where 0 are on all the three axis. Or can I just delete 900 lines, of cause leave the start up lines and start from there?
Hope someone can give me some advises

General Mach Discussion / SmoothStepper USB and Mach3

« on: August 26, 2015, 02:10:40 PM »

Hi I have Mach3 version 3.043.066 that has ruined ok for a long time but I have suffered some crash or just freeze  in the middle of the job. I found that SmoothStepper USB could help avoiding this problem so I got me one. I read that I needed Mach3 version 3.043.062 in order to avoid problems. I have installed the SmoothStepper on Mach3 3.043.066 and have problem with homing and limit switch on the Z axis. In Diagnostic window all limits and home switches is working ok.

Reading at SmoothStepper forum I found that my Mach3 version could be the problem. Than my question is? Do I have to uninstall the Mach3 and reinstall the older version afterwards? What about the license?
Thank you
Gaute

PS I use the Mach3 on a combined 3D printer/router.

General Mach Discussion / Can not get A axis to run

« on: January 21, 2015, 02:35:25 PM »

Hi
I´m using A axis to run 3D extruder head but can not get A axis to run. I tried to use A axis as the Y axis slave but never got it to run so I used B axis as the slave sucessfully. I recon it was the break out board so I replaced it with a HG08 from cnc4you. In the diagnostic screen pin 7 from top from right is green but for A axis it is pin 8 and 9 that is used. Are there any special settings for the A axis that I have missed?
I have runned Mach3 successfully as a router so I´m familiar with the settings. I have checked the cable and all the pins are ok. Could it be the computer port?
Hope someone has an idea.
Thank you
Gaute
