Mesa 79i6s CR8 (yellow) was created by Tom369

Mesa 79i6s CR8 (yellow)

Category: General LinuxCNC Questions

Hello,
The Mesa Card is glowing yellow, I believe that must be the CR8.
I measured exactly 5.00V with a multimeter.
Does anyone have any idea what this could be?
Thank You
Best Regards Tom

OK, at this point I think I need to rip out this junk, out of production, no clear manual VFD and buy a new unit that has a video on how to set it up. At least that will eliminate one variable as I have no way of knowing if it was ever set up correctly and that subject is way off topic for this forum.

So if I can get a VFD that I can program and setup correctly, you all think what I have for a configuration will work then?

added ini:

added hal:
net Y_HOME remora.input.09 => joint.1.home-sw-in joint.1.neg-lim-sw-in
Work!


I still need to figure out why the home search has to be done so slowly.

When I hook a multimeter up to the vfd 10v in, the voltage physically drops near to Zero if a lot of speed adjustments are done. So I can see now what is happening but iv no idea why the voltage drops so much. It must be something to do with how remora outputs the signal ? 

Thats what we needed to see, but this is somewhat expected by the reading from the halscope of SP.0 . alright, well this can be 2 fold. either the RT1052 firmware is doing it, or the analog circuit is messing up. It doesnt show up on mine because Im using STM32 firmware, and Im using PWM.

I am try homing and limits.For test i have only Y stepper driver installed.
Homing work.
but i limit stop not work. I need for safety and bad moves.

hal:
#Homing and limits
net Y_HOME remora.input.09 => joint.1.home-sw-in

ini:
[AXIS_Y]
#MAX_VELOCITY = 100.0
MAX_VELOCITY = 30.0
MAX_ACCELERATION = 30.0
MIN_LIMIT = 0
MAX_LIMIT = 30000.0

[JOINT_1]
TYPE = LINEAR
HOME = 0.0
MIN_LIMIT = 0
MAX_LIMIT = 30000.0
#MAX_VELOCITY = 100.0
MAX_VELOCITY = 30.0
MAX_ACCELERATION = 30.0
STEPGEN_MAXACCEL = 30.0

#HOME = -10.0
#HOME_SEQUENCE = 2
#HOME_OFFSET = 0.0

HOME = 1
HOME_OFFSET = -3
HOME_SEARCH_VEL = -10
HOME_LATCH_VEL = 30
HOME_SEQUENCE = -1
#HOME_USE_INDEX = False
#HOME_IGNORE_LIMITS = True

forum.linuxcnc.org/plasmac/46160-homing-...ctive-before-backoff
linuxcnc.org/docs/devel/html/config/ini-homing.html

what do i need to do to make the limits work?
Why doesn't homing lock the stepper instantly and needs a monstrously slow motion for the initial search?
