Art: Thanks for info. I think the offsets are not being removed from X axis on M30. It resets to a value equal to original position + (or -) last coded position. Tom pulse occur, if zero?

Hi Art, I'm using spindle Step/Dir with V7.2, just changed from M1 where spindle was OK, this is mill. Using 25Khz kernel freq, calibrated FotV at half speed VFD op = 60hz,increase speed to 3/4

Have you cut any threads with the latest Mach2? Jerry

Art, You can also load a file, jog 10", zero all or zero the axis you jogged, hit the regenerate button and the extrema will be off by 10". Todd always file

Having Spindle correction at all times...Hmmm... Perhaps. The problem is I use the actual feedback when a G32 is started as the start speed and correction is done during the G32 to correct stepper

Hi again, The z has to be at any # other than 0 ( say 2" before you start the g28.1z1, just type the g28.1z1 into the mdi window twice and you should see it happen. Thanks Todd move the time Can

Hi Art, While you have the first file open move to any location other than 0,0,0 and do a zero all, close the file and load a new one and the extrema will have wild min #'s instead of 0 ( my x & y

Yes - works fine on mill, just been and tried it, it's within + or - .05V on 20 attempts with lathe hardware. Reset toggle doesn't affect spindle on either. Ohh - anything stopping this being an

Thanks Steve: Does the spindle speed work correctly in Mill on yours. (I was using mill to troubleshoot this one, my mistake..) Speed correction is only turned on in G32 move. This is independent

All Step/Direction spindle bugs V7.2 lathe The problem I have, is although they are being generated the steps out are reverting to some arbitrary value. Although Mach2 seems now to be storing the

Hi TorchHeads: I need help with this one. On my system G28.1 Z-5 for example will move the Z to relative Z-5 and then do a homing routine. This is repeatable time after time. How can I make it do

Todd: Can you explain this further, I cannot repeat it, when I load another file, the extrema changes to reflect the new file. Is this RC2 or 7? Art www.artofcnc.ca

Hello All: I have quite a list of small bugs and problems for next release. Please hold off on any feature requests until after next version. I was only away for a wekk, but the volume of mail is

Hi Frank: As a test lower the Z acceleration. This is the most common cause of this. Rapid reversals of the Z is notorious for lost steps due to the huge inertia of the Z axis. Usually it is the

Hi Jeff: Not yet possible, but hopefully will be as I get time. My list is very long for the next version, but as soon as I can clear it all away, we'll look at what can be

Hi Tom: I don't know whats causing the slowdown, check to make sure the pulse width is not too high. If set to 0 or 1, the slowdown should not occur, if set too high, this may cause that type of

There are a couple of ways of doing this - one way is to drive the pot via stepper using step/direction. The other way is to replace the pot - generally the three connections go +10, set speed, 0V.

Brian Tried to send this direct so you could get the attachment but your e-mail bounced (twice) I think that the attached macro (not with this post as Group will not allow them) coded for test as

Well I thought I was home free and over the hump when I got the three axes running off one port on the laptop (Compaq 1510 2.2Ghz P4) with Mach2 RC2. This a router running simple rectangles,
