Intermittent lost steps
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,

Re: question for art
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.

Re: 35kHz slowdown, bugs
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

Not yet possible, but hopefully will be as I get time. My list is very long

Re: Intermittent lost steps
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

Re: Extrema
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?

G28.1
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

All Step/Direction spindle bugs V7.2 lathe

Re: Problems and features..
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

Re: Problems and features..
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

Re: Extrema
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

Re: G28.1
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.

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

Re: Extrema
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".

Spindle speed - more data
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

Re: 35kHz slowdown, bugs
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.

No, afraid not - impossible until step/direction speed control works
