Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

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?


the gain thing was my mistake, they are both the same. remora outputs pwm, and if your hardware has a 0-10v, it will convert it to analog with the op-amp hardware circuit. digital signal might be referring to PWM

Those drives can not do more than 3-3.5A, but that might still not be the issue, i doubt the new motors are of very high inductance, so can you measure the resistance between the windings?
The old motor, is it unipolar or bipolar? How many wires does it have?
If 5 wires = do not use with new drives
If 4 or 6 or 8, try to use it with the new drives, just mind the windings.

Those should be in the ini file, the DISPLAY and TRAJ sections.

hey spyder, the y axis is the one you want to copy, that sounds like the proper one. , so after it homes, i think home offset is where it goes after homing. if you set the home offset to be off the switch, it should be able to home the next one. observe how and where your y axis is going, and copy it to the other axis, it will involve inverting these numbers to be negative or positive. refer to the manual for verification of which direction does what.
HOME_OFFSET = 1
HOME_SEARCH_VEL = -2.0
HOME_LATCH_VEL = -1.0
HOME_FINAL_VEL = -2.0
HOME_SEQUENCE = 1

If anyone thinks this should be in it;s own thread, let me know, but I still have a few questions about the GUI.

There are override sliders for max velocity, rapid, feed rate, and spindle. The max velocity and rapid default at 100%, shiny. The problem is that 100% is about 3X more than my machine can move. It says its 12000 for both. Need to be set at ~3600 each. Been looking through the config files and I am not seeing those numbers anywhere. Where do they come from?

Off On Off Off Off Off which is 8 steps as I have it configured in stepconf and max current which i believe is 4.2 A with the TB6600. Nothing gets the slightest bit warm. Original stepper was a nema 23 but round bodied and smaller than the 425ox (I only have one, The guy I bought it from had removed the Z stepper and fitted an electric drill to the shaft).

What are the drives set to?
What motors were there originally?

Homing and limit in one switch.

In the ini file
HOME_SEARCH_VELOCITY
HOME_LATCH_VELOCITY
HOME_FINAL_VELOCITY
Any of those you have, set to some reasonable value in machine units per second.

I'll try and find my old .hal file for my mill tomorrow , I  got that working with prox and limit switches, I think they were all wired to one input also. It was with a BOB though not remora 

I think it homes one axis at a time. Hits the switch backs back off again a set amount. Then moves on to the next axis and so on 
 

Yes, that is how my homing works. Z first (don't want anything attached to the bed to crash into the head, then X, and finishes up with Y. That part works great, with a little odd behavior with the Y as it for some reason hits, backs up and comes at it again real slow, like it's probing, then jumps off a few mm and zeros like the other 2 axis. Attempting to add in the limit sw config, Z will home properly and then reports that a limit switch was tripped and the homing process is stopped dead.

Which kernel version is best for real time?

8GB of dual channel ≥1333MHz RAM is fine.

Just making sure you're not trying to get by with like 2GB.

Whoa!

Don't desolder stuff!

You said Realtek card, not Realtek chip!

Cards are easily removeable, chips generally are not.

Don't mess with the motherboard.

The 7I96S has two internal voltages regulated down from the 5V supply
3.3V and 1.2V The power LED monitors the 3.3V used for most logic.
