losing notification-messages from the stepmotor devices
October 17, 2007 09:04AM
the stepmotor-devices are not sending notifications if the motor reaches the min-sensor during a dda-operation.
e.g.
in stepper exerciser:
home for x and y
line test: to x:700, y:700 (moving ok)
line test: to x:0, y:0 (moving ok)
waiting for notification until timeouts
(then x has the value 1 and y the value 3)

i get the result with the standard firmware version 1.0 (and with my new version).

i think the problem is, that in the function forward1() the variable function is set to func_idle if the min-sensor is reached. after than, no notify is send in the timerTick() function.
Okay, good to know. Can you fix this problem?

Andreas,

I programed and ran V7 last night and it seemed that can only run my x and y axis in one direction?? It might be me also tonight I was going to try the one that is on source forge as a base line to see if that works in both directions since I just rewired my stepper motor (my X was not the one that was reversed it was my Z)

So I will let ya know.

MY bad, I found I had the min. "end stop jumper" on the wrong pins. When I was testing the Robot I am pulling the end stop pin to simulate the end stop till I get the time to wire and install the end stops ( hopefully this weekend! )
so all is good I al running V7 of the firmware and all seems to be running well..
