Thanks Pietro -
How can I find this out?
There is an option in input signals that says "automated setup of input signals"
Is this were it is done and how do I use it ?
Otherwise please advise how to do it

General Mach Discussion / Mach3 home not working

« on: January 31, 2020, 12:08:50 PM »

Hello everyone. please help me sort out a b.up that I made
I have been reconfiguring my Mach 3 because I fitted different pulleys
and needed to recalibrate the steppers.
I changed something in ports and pins and now the home function doesnt work.
when I select HOME X the slide moves correctly until it engages the mechanical
home switch and then it stops and switches the emergency stop LED to flash.
it doesnt move back off the home switch as it is supposed to do.
Anyone know what I could have done?  where should I look?
when it touches the switch i have to move the switches cam off the switch,click the emergency
stop switch off and then move the cam away from the switch manually

General Mach Discussion / driver test resetting pulse speed?

« on: January 26, 2020, 05:37:33 AM »

Hello Chaps
Just upgraded some stuff and now i am resetting etc.
A question
Using drivertest and selecting 35000 mhz .
when I press enter it jumps back to 25000mhz?
what is the difference between 25000 and 35000 anyway.
the book says use 35000 mhz .
best regards

Hello Everyone
I am trying out different tools with speeds and feeds to see the difference
in cutting
I have written the attached bit of code but wheb I run the code when
it hits the block M3 the speed runs away up to maximum speed (1700rpm)
Would some-one please look at the sample of code attached and tell me why it should be doing this?
( sorry i am battling to get the code to attach so am doing a copy paste)


% prepare
% take one cut along the diameter
G18 (xz plane)
G40 (cancel nose radius compensation)
G49 ( cancel tool offset -like at a tool change)
G80 (cancel all canned cycles)
G90 (absolute distance mode)
G95 (move in units per rev)
G80 (cancel canned cycles)
s300    (motor speed set to 300rpm)
f0.1   (cutting feed is .1mm per rev)
m03     (start motor forward)
g0 x58
g0 z5
% first cut
f0.1
g0 z1
g0 x58
g01 z-15
g0 x60
g0 z1
M30 ( end of program return to program top -same as m02)
