General Mach Discussion / reverse axis
« on: September 21, 2010, 08:52:50 AM »
hi all,
is there a setup in mach to make my x axis go in the opposite direction after installing a new board the y and z are ok but the x is going the opposite way to what it used to,i have checked the wiring to make sure its the same as the others and it is ok its probably just a daft switch somewhere in mach but i just cant find it, or do i have to turn the motor around?
thank you.

General Mach Discussion / Re: help with motor torque

hi rich
thanks for the reply the board was set at 75% so i only had one more step up,after setting it to 100% the z worked ok although the motor sounds like its missing a step every now and then but the measurement is ok also the motors are making a little nose when standing still, i worked the z up and down for 15mins and the motor was only warm so i guess this is ok i left it for one hour and the motors got a little hotter but i could keep hold of then with my hand no bother.
i will take a look at the geco site as you suggested. thanks again for the help.

hi,
thanks for getting back my settings are 1 on 2 off so if I'm right I'm running at 75% so if i set them both to on i should be at 100%
told you i was new to all of this, the motors have no names or markings on them so i will just have to take the chance they will be OK, there a good size motor and like i say they were alto harder to turn with the old board so must have been getting more juice.
thank you again for your help

hi thanks for the replays I'm not to sure about the specified motor current for my motors they dint have anything on them but i will take a look at the board to see if there is some adjustment and take it slowly. this is the ebay number for the new board i got  250682276810 if you can see any adjustment please let me know

as for the old board there is nothing wrong with it after my pc went down i had to reinstall mach3 and i never had the board settings so it worked on screen but the motors never went around knowing nothing about cnc i thought it would be best to go for a new board with the settings .the old board and motors were bought about four year ago.

hi all,
I'm new to cnc so still very wet behind the ears so please forgive me if I'm not making any sense i will try to explain as best i can.
i bought a cnc router with the intention to use the motors and board on my mill i put the z axis on the fine feed as i didn't think the motor would be strong enough to lift the whole head (i think the motors are about 400oz)but there was to much play in the spindle unless it was locked off every time,so i made a rough coupling and with the motor held by hand tried it on the column and to my surprise it moved the head up no problem at all.
then while trying to make a bracket i had bother with cambam and mach i couldn't get a circle cut, then my pc went down when i got it back up and running i had lost all the settings for the board and the whole thing was dead in the water.
so i bought a new board (TB6560AHQ) and every thing was ok i got cambam to work with mach and made the bracket for the z axis but now the motor will not lift the head it just makes a clicking sound its as if i have lost some power from the motors, i did notice with the old board when the power was on and the motors lock up it was hard to turn the mill handles but with the new board it seems easier to turn them, i have tried adjusting the motor velocity and acceleration so its just going slow but this never made any difference.
any help would be great thank you.
john
