 Bingo, I changed the homing speed and it looked really good.
 Only the issue of homming is still 'strange', sometimes it does homming on the three axes, sometimes it only does it on X and Y.
 I couldn't understand now how to homming each individual axis...

Ah yes, Bananananas. I recall someone from Aus calling them that. But, he still does a lot of work in bananas!

thanks for the feedback!

i have two drivers where i can't activate enable! i don't have the schematics for these drivers. I took care not to disconnect the control cables (motor, tachy, enable, etc...) after wiring with my 7i97 board.

the only thing that works is the fault relay.

 

 

That does not seem to be a +-10V servo drive
but rather a SCR DC motor controller that
depends on AC for commutating the SCRs
so even if it had a +- input would be very
sluggish in response to commands

What is wrong with the current drives?

I get this error when using remap m6. I am using VERSA Probe version 2.9 and LCN version 2.10

Near line 0 of/usr/share/axis/images/axis.ngc:
pycall: remap.change_epilog:
Traceback (most recent call last):

File "/home/router/linuxcnc/configs/fresadora_MS3_VP/python/stdglue.py", line 200, in chan emccanon.CHANGE TOOL(self.selected_pocket)

I don't think anyone has worked on DC mk2s drivers.
so I'm going to look into some new drivers.

i found a repairer of these drivers but i would like to compare with more recent drivers.  

but i'll need help not to make a mistake because the price is expensive and my motors are quite big!

my two motors have the following characteristics

Motor : NUM motor
Type : 40-P4-61
Series : 6904
Constant torque : 6 N.M
Max RPM : 3000
Volt : 183V
Pulse AMP: 63A
Tacho : 9.5V/1000 RPM

so I need to find a new driver that should deliver

- a voltage of 186 V max
- a rated current of 27 A (old driver carateristics) and a current pick of 63 A
- tachy input
-must be -10V +10V driver

am i forgetting something?

as below, i've found a driver with the following characteristics:

-an output voltage of 180V if powered in 220 two-phases or 220 single-phase (I have both on my cnc)

-a max current of 32A and accepts a 150% peak, i.e. 80A

so far so good, but my questions are as follows

- in the specifications it talks about 0-10V input, but on the schematic you can see that it's marked CW and ACW, so is it compatible with -10V +10V?

 


 

-I can see data from the tachometer which is "speed feedback output 0 to 7.5V" and my motor is 9.5V. What should I understand from the tachometer characteristics?

 

- Finally, is this really a DC driver for my motors for axis use or is it a kind of VFD for DC motors?

 

Done
 

oK lads I have got made a thing.

Hope this will help somehow

Hi Chris,

Would you be willing to share any experience / knowledge on how you did the Fadal retrofit?

It would be awesome to learn from someone with experience. 


Thanks,

Frans

Hi msrdiesel,

Are you using this 3D probe in combination with your Retrofit Fadal?

Interesting setup

It may have been the fault of mine, I changed the flash chip out, it may have been a dodgy one. I'll chase up an original M25P40 and put it back on.
In the meantime I have access to a few other Spartan6 boards, one with the same FPGA on it, pins are just a bit different and only 70 GPIO available, but does have 6 LEDS and 4 switches on the board
Al least I'll still be able to experiment, got plenty of dupont cables to patch the FPGA board to my daughterboards.

Thanks for all your help, changing things around is pretty straight forward, and after messing with the Mesa firmwares I feel comfortable messing about with it.

Yes, laser marked parts are hard to read unless you have the light just right...

U10 26LS31 (SOIC16)
U12 74ACT540 (TSSOP 20)
U15 26LS32A (SOIC16)
U19 74ACT541 (TSSOP 20)
U24 74ACT04 (SOIC 14)

have update the board config in git and build and upload a new bitstream file.

i have the same problem with openFGPALoader and MachXO3 from lattice

Is there anyway to do this automatic? I have read about event handlers but running it in the background seems kind of a waste. Maybe update it when the tab gets activated (clicked on) ?

The most elegant way would be to load this on a file-load event. signal "file-loaded", see linuxcnc.org/docs/stable/html/gui/gstat.html.
But if I remember correctly this doesn't work with GladeVCP unfortunately. Therfore the HTML widget must be part of Gmoccapy.

What does this window contain?

20Mb for a file system image ??????

I wasn't asking for a kernel image but a file system image. Can't chroot into a kernel image.
