DDSCV1.1 3 and 4 axis offline motion controller

[Will_D]

Never knew about a "Find Center function". How is it invoked.

I have written a test sub-routine:

(Safe Block)
G17 G21 G90 G54 G40 G49 G80

(Investigate Subroutines)

(set initial X, Y and Z)
G01 X0.0 Y0.0 Z0.0 F100

#1 = 3.888

G01 Z2.0
G01 X FIX[#1]; Round Down
G01 Y FUP[#1]; Round Up
G04 P5000; Little delay

(Note the above has nothing to do with testing the subroutine mechanism!!)

M98 P456 L3; Call subroutine 3 times

M30; End main Program
%

(Declare the Sub)
O456

G91
G01 X2.0 F50
G90
G04 P3000; Little delay

M99; End of Sub
%

The find center function can be used by redefining the start button. It can be set in parameter #446

Hi,

First post - and I'm sorry if this is not an appropriate location/method of seeking advice.

I have recently completed the conversion of a Sieg Mini Mill and am using the DDCSV1.1 controller (Madmodder Flashed).

Surprisingly - everything seems to be working and a test gcode sample appears to be doing what I had hoped it would. I have yet to cut any metal with it but that will happen soon I hope.

There is one aspect of the function of the controller that is currently bugging me - that is the Homing Function.

I have proximity limit switches on all the axis and they appear to be functioning properly - but when I invoke the Homing Function the following happens:

Z comes down to limit switch then goes up to upper limit and stops (Unit displays "Z-axis pos limit trig'd")
Then
X moves to neg limit switch then goes back to pos limit and stops (Unit displays "X-axis pos limit trig'd")
Then
Y moves to neg limit switch then goes back to pos limit and stops (Unit displays "Y-axis pos limit trig'd")

leaving all axis at positive limit.

Is this whats supposed to happen? The values on the DDCSV do not reset and the axis do not back off the limits. Is this whats supposed to happen?

I would be very grateful for any advice.

There is an adjustment if the axis should try a couple of times homing, then back off after homing and where the homing happens. Hard to guess more, as you use modded controller.
