2.9.3 - Stuck in wrong state and stops

Category: Plasmac

Thanks for trying. The hal files you bypassed are all well tested and are all for specific hardware so you could not implement them.

When you say that the velocity and acceleration is incorrect, I think you are expecting to see the axes values higher than the joints to allow for external offset ratio. But in practice, that is not necessary. I have them set as I always have since before external offsets was pushed to master 7-8 years ago.  After all, I was the one who worked out that we can double velocity and acceleration and use a 0.5 ratio because THC is mutually exclusive with gcode motion. The author of external offsets had not thought of this at the time. This was a major discovery that enabled THC control and ultimately qtplasmac without compromising velocity and acceleration.

I might add that there were a lot of constraints due to the machine design that we retrofitted with showstopper but the owner is happy as one job that took 2 hours now only takes 20 minutes because of QTplasmac.

Its little things like this that prevents him walking away from the machine on his lunch break! Hopefully, we will find a solution one day.

I had not installed any locales. I was under the impression that it was already in english as default. It was C.UTF-8 as default.
I installed en_US.UTF-8 and chose that as default.
Now it works!
Thank you!

That index helps a lot. For a newb like me it is hard to find the relevant info in all of these threads. I guess it becomes a lot clearer when one has spent a few hundred hours on here :)

Next step is to connect some stepper drivers to confirm that the setup works.

Help! why my feedrate is so high? 4500000mm display in gmoccapy!

Category: EtherCAT

I found that the high feedrate is made by "#<fscale>=10000" in linuxcnc sample ngc file. thanks

Question about custom BOB for a 7i92

Category: Driver Boards

Thanks.

I just remembered about the 7i92T I have laying around with the half dead FPGA. Looks like the Trions are in-stock at Digikey. Anything special need to be done other than just swapping it out?

Edit: I flashed one of my 7i92t's with the new firmware and all of the the pwmgen output pins are missing. They're shown in the startup printout, the pwmgen enable and value pins show up in hal and the gpio pin it replaces only has the hal inputs of those pins but no output pin?

One of my 7i92t's is suspect, the other one is dead but this seems like an odd thing to be a hardware issue. this one otherwise seems to work after flashing.

Hello, 

Is it true that release 2.9 and above has S-curve implementation in it (As per Ai world). 

just need to add "SCURVE = true" in Trajectory Planner section...

If its true, what other paramaeters can be set in ini file..

thanks,

Hi Mark,I watched you re-grease the spindle on Youtube. I don't have much luck there as most of my post are removed in a few seconds. I haven't figured why.But I noticed your bespoke hand wheel. On mine it is held on with an off the shelf detent. Easy and neat.

Possible retrofit of a Körner Magic550 CNC Machine

Category: CNC Machines

Do the motors have tachos on them and what voltage do they output?
Encoder incremental 1Vss does not seem right, should be TTL level normally so 5V or more.
1Vss is ok for resolvers although they can do more...
-
Scour ebay.de for Kolmorgen, those can be found for good prices although last i looked was probably two years ago.
But you do need to have the above info correct before jumping in.

2.9.3 - Stuck in wrong state and stops

Category: Plasmac

I made a sim from your config and after lots of testing I was unable to replicate the issue.
It should be noted that I did not test pendant, ohmic, or step boost, I commented these out and also replaced my_Plasma.hal with sim_no_stepgen.tcl which is the standard QtPlasmaC sim hal file. I am only able to test in a sim as I have no hardware. If you can replicate it in a sim then could you post the sim and the workflow that causes it.

I did note that in showstopper.ini the relationship between the MAX_VELOCITY and MAX_ACCELERATION settings for the X, Y, and A axes and  their corresponding joints are incorrect.

I've forgotten the exact debugmsg at that time. I obtained the information for this issue from the diagnostic LED provided by the manufacturer. The specific content is: Invalid parameters were written.

Possible retrofit of a Körner Magic550 CNC Machine

Category: CNC Machines

After some extensive googling  and some back and forth with some Servo+drive manufacturers we are still searching for Motors and drives. In the mean time we striped everything of the machine and we found that the installed Servos were smaller than the ones specified in the schematics.
All the servos are the same ,Heidenhain QSY96G which have 1,4Kw and a moment of inertia of 6,3kg*cm2..I have found similar servos but with about 25% less moment of inertia. Does this influence noticeably the acceleration/deceleration ramps ?
Another thing that I found out is that servo motors, annoyingly, don’t use the NEMA sizes .It’s like the potatoes in an organic food store, everyone a different size.
I am gonna put here the specs of the QSY96G servos maybe someone can help me find suitable Drives .
power 1,4Kw
voltage 291V
current 3,3A
torque 3Nm
max current 25A
max torque 22Nm
moment of inertia 6,3kg*cm2
encoder incremental 1Vss

custom button

Category: General LinuxCNC Questions

Qtdragon uses Qt so glade is not so useful, it would require QtDesigner.
There is a button to turn a laser on and off that is included in QtDragon.
The button is on the offsets tab. the pin is qtdragon.btn-laser-on

If that is not what you want there are more options, such as macro buttons.
Customizing the screen layout with extra buttons is not super hard - where would you want the button?

Did you save the file after changing it and restart lcnc after editing the file?

The "set wco rotation" button must be active when the probing routine is started.
