General Mach Discussion / Re: Help needed for Y axis error
« on: April 10, 2016, 03:30:04 PM »
I have made an error, the machine also jogs backwards. Is there a way in Mach 3 to reverse axis direction in the software? That would fix the issue..........

General Mach Discussion / Help needed for Y axis error
« on: April 10, 2016, 12:29:57 PM »
I have a new machine and have loaded a program I have run many times before. This has me baffled and perhaps just a software adjustment can fix the problem? When I click down thru the program one line at a time, it drills first the center hole, then the second hole on the same plane as the center hole. The third hole is CCW rotation etc. BUT! when I  hit run the first hole drills correct and the second, because on the same plane, the problem now comes for hole number 3, the machine does the bolt circle by does it CW or backwards from the program. This produces a correct piece because it is a circle. but Y is going minus where it should run plus. The machine jogs in the proper direction?? Anybody have any ideas or cures for this? AT this point it would be impossible to run any program correctly...............

General Mach Discussion / Re: spindle control
« on: April 04, 2016, 08:37:40 PM »
Tweakie,

In your above post with the pic of the motor control and the arrow pointing. Do you mean to change red X to green arrow to fix this issue? I am having same problem with my new machine and it will only run CCW regardless if I use M3 S2000 or M4 S2000. While I have you, the spindle comes up to speed very slowly, I fear the spindle will not be up to speed before it starts to drill or mill. Any suggestions on that? TIA

General Mach Discussion / Re: Z axis problem, HELP!

Hood,

Thank you for replying. I am having the same issue and now I am convinced its a temperature issue and a controller issue. If I swicth the plugs around the problem moves from Z to X. Now that it has been ober 90 degrees, the issue is really bad. I am sending the controller back to be checked.

One thing puizzles me is that you were the only one to respond, while another user has a ton of attempted help and its a HOT TOPIC. I know us small time contributors have little to add to the forum, but when something like this happens to you, its very much important.

I'll post a reply when the controller comes back........................

Hood, thank you for the reply. The second tiny movement is what is throwing the Z height off. I jog up after finding zero and when I remove my finger from the keyboard, it jumps a tad more. I switched the cable from the Z to the X, to see what would happen and then it also did it in the X. I think that rules out a bad servo motor, as X works just fine. I am leaning towards the controller?

Is there anything inside computer that I should change values on possibly? This quirk just showed up recently and never happened before.

Thanks in advance for any other suggestions.

Maybe this bit will help, it seems this anomaly only happens on the first up jog, second or third up jogs, don't seem to be effected???

General Mach Discussion / Z axis problem, HELP!
« on: June 01, 2012, 11:51:15 AM »
Last week when I was running my machine, when I jogged up the Z after setting zero, I noticed the Z would change and not hold. I then looked closer and when I jogged the z up, it would make a small second movement. I called and ordered a new servo motor for the machine and when it arrived, I went into the garage and the Z was working fine??? I then cut about 30 pieces with no issues and then it started again. The z would change with each jog after setting zero. That little extra up bump I would notice on the hand wheel. HAs anyone else ever had this problem. Where do you think I should start. I am at a loss here. I am using a tabeltop mill made by Townlabs and it uses servo motors for all axis. THank you for any help...................

General Mach Discussion / Re: Noob ? on cutter comp
« on: May 21, 2009, 03:38:35 PM »
That was my firsts thoughts too. SO, I checked that first with a 3" gauge block and also checked backlash, both appear to be correct. I am using servo motors and steps are about 12K.

There must be some software trick I am not doing. My thinking is that because when I changed the tool diameter it did not change accordingly, again irratic numbers.

General Mach Discussion / Noob ? on cutter comp
« on: May 21, 2009, 02:31:08 PM »
I am using Mach3 and am getting irratic measurements. The piece will be off .040 over on one spot and .100 on another. I checked and all  code is correct. I am sure I am overlooking something. I had a .125 cutter in the mill and it was .050 over, so I changed cutter diameter to .100 and it only changed .020? I should not have to amend every measurement to get what the print says.

Why would an X number be off .050 and a Y number be off .100????

HELP PLEASE!!
