mach4 bug and other question
First there is an annoying bug in mach4 that i can work around but often forget and i did break a bit because of this. I am using cheap bits but as of a few days from now I will be using very expensive bits and do not want to break them.
When you boot mach4 the step increment is shown in the jogging pane as what was previously selected. However the increment really is 1 in spite of what is shown. So when i get real close with the xbox controller and then want to make a .01" adjustment, it moves 1 inch instead which can cause it to crash. All i have to do is to remember to set the increment again but i keep forgetting. I have shared home and limit switches for three of the four axis. Everything works normally with the exception of one switch in one direction. If i hit a limit one of two possible things happens. On the z axis if i run into a limit it backs off or at least stops trying to pass the switch. i can then back off in the opposite direction. on other axis it triggers an estop and i need to enable again before i can back off. However on the X axis if i hit the limit in the on the left it behaves as expected. if i hit the switch on the right it triggers an estop and there is nothing i can do to move that axis without rebooting mach4. resetting the enable does not allow jogging off the switch. This is the case for just the x axis on the right. I had not noticed because i never hit the switches, i was just testing. -- Best regards, Spencer Chase 67550 Bell Springs Rd.

what about that x axis issue? i can not find any setting to try and the strange thing is that it is just this one direction on the one axis.

what MPG do you use? i am having fun with the xbox thing but could certainly use something better. BTW, i have been cranking out parts and have had maybe one or two strange glitches that were probably windows related but no broken cutters or strange behavior.

Spencer_ You can put a line in your startup script to set the jog step increment to whatever you want it to be.

but will it match what is displayed when the program boots? the display shows .01" and the actual value is 1"

The issue with the limit switch is that it has no idea that you can hit the same limit switch in the opposite direction of travel. In cases like this you need to override the limit input. I will send it over to the support guys and see what they have to say. As for the incremental jogging, that has been tested by the support guys and we are going to see if we can get a fix done today for that.

We will see if that can make it into the next release! Thanks Brian ______________________________ Brian Barker Engineering / Devlopment ArtSoft | Newfangled Solutions Livermore Falls, Maine (USA) Phone: 207(618)1449 Webpage: On 5/14/2021 12:52 AM, spencer@... wrote:

Jogging issue is fixed and commited, The issue was we where setting the jog in but not setting the index in the array that holds the jog increments. Nice little one fixed :)

No big deal if i need to override the limit but i have? not figured out how without rebooting mach4. i can put a switch on the limit switch but then i will forget to turn it back on.

on the z axis i am pretty sure that trying to move to the limit mach4 automatically backs off even if you keep jogging to the switch repeatedly. the one exception is the x limit on the right side. if i jog to the left limit i can back off after reactivating. it seems that mach4 does know the direction of travel when it hits the limit but only in the left moving direction on the x axis. i tried to program a motion machine to work with just on limit switch for both directions and as simple the algorithm should have been, i never got it to work right,? so don't ask me to fix it :) On 5/14/2021 7:22 AM, Brian Barker wrote:
