Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

I think that's explained in the Linuxcnc manual. If you look in that it may explain how to do it. What mill is it ? My .hal file I uploaded a few posts back. Have a look at that. It's a lathe though. I'll be starting my mill with remora next month.  I'm waiting for parts to arrive, to build a circuit to drive the 12v stepper drivers  first. My mill has limits and prox sensors.

For now I'll address the next question I have. My machine was built with all 6 proximity sensors wired in series inside the machine with only 1 wire for signal. Homing works but any attempt to add the limit switch part in results in a failure to home after the first axis, saying that a limit switch was tripped. Reading through the forum, I saw a few mentions that it should be possible, but there were no actual examples of how it is done. The best I found was one with all 3 homes on one pin and all 3 limits on another. For now it is moving OK, (I figured out how scale works) and got it set right. Tell it to move 10mm and it moves 10mm. so I can fall back on the soft limits... Better than nothing.

Thanks Cakeslob, I forgot your using the stm32 :/ the code in the hal file is the same for 0-10v and PWM ? Just the gain determines the difference?
In my VFD there is an option for 0-10v, 0-5v and external digital signal. Is it 0-5v or digital signal for PWM ?

@scotta , any ideas why it's doing this?

I wouldn't give up on the VFD yet, if it requires 0-10v it should work. I think you can test it externally with a potentiometer. Post your .hal file. You can hook a multimeter between com and AI1 of the controller . If that's still 0v there is more than likely something wrong with the code.

Look at remora.sp.0 in halshow and see what it's doing when you adjust speed

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.

Homing and limit in one switch.

Category: General LinuxCNC Questions

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
SCALE = 160.0
FERROR = 1.0
MIN_FERROR = 0.5
#HOME_SEARCH_VEL = -10.0
#HOME_LATCH_VEL = -3.0
#HOME_FINAL_VEL = 20
#HOME_IGNORE_LIMITS = YES
#HOME_USE_INDEX = NO
#HOME_OFFSET = -20.0
#HOME = -10.0
#HOME_SEQUENCE = 2
#HOME_OFFSET = 0.0
#HOME_SEARCH_VEL = 50
#HOME_LATCH_VEL = 50
#HOME_SEQUENCE = 50

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

I read:
forum.linuxcnc.org/38-general-linuxcnc-q...tches-is-it-possible
forum.linuxcnc.org/38-general-linuxcnc-q...ng-on-a-single-input

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?

sorry spyder, i had a provision set up so you could do everything from ini file. just sawp these 2 lines, uncomment the one
#setp scale-rpm.gain 0.02 # 100/ rpm (5000) = .02
setp scale-rpm.gain [SPINDLE_0]RPM_GAIN # 100/ rpm (5000) = .02

for the outputs, yeah you need to change them to whatever your outputs are

Which kernel version is best for real time?

Category: General LinuxCNC Questions

Did ya set the governor to performance?

Try to remove unnecessary hardware.

blacklist kernel modules of unneeded devices.

Mask and disable unneeded services.

Ensure you have plenty of RAM; disk I/O should be avoided as much as possible.

Caching and buffering will reduce disk I/O and latency, but requires ample free RAM.

need more of 8Gb ?  i need desolder realtek from my motherboard?

Which kernel version is best for real time?

Category: General LinuxCNC Questions

Yes PCW, is the same Realtek with dkms driver for fix latency.
Maybe I'm asking the wrong question: is it really necessary to do the test with YouTube?

When you get an error, what does:

halcmd show param *.tmax

(typed in a terminal)

show?



 

 
next youtube video start i take junction error.

Actually, no. Spindle 'ON' shows 0v between COM and AI1.

Moving from Axis to QtDragon?

Category: Qtvcp

Had a bit of a break and thought a minute and I think I figured this out. There is an entry [FILTER] in the .ini file and I added a line below that PROGRAM_EXTENSION = .nc,.ngc,.gcode G-Code and not only did that work, placing it first in the list makes it the default. Very nice. Thanks for that bit of info. Much appreciated.
