From .iso to build

Category: Installing LinuxCNC

Dear Forum,
I started out with the .iso of linuxcnc. Configured my machine with Pncconf Wizzard and realized that I have to compensate for the geometric imperfections of my machine. There are some clues in the forum:

forum.linuxcnc.org/10-advanced-configura...t-axis-errors#105999
forum.linuxcnc.org/10-advanced-configura...onent-and-hal#191290

I'm thinking of writing a custom Kinematic module that takes a Table of commanded Positions vs. measured Positions  and generates (interpolates) the correction and commands the motors (closed loop steppers) to the correct position.

What is the best way to do that?
Do I have to compile the whole LinuxCNC myself?
Is it sufficient to compile the kinematic module? 

with kind regards

Martin

7i97t with 7i84d connection problem

Category: Driver Boards

You could check if there is 3.3V power, and if not, maybe trace
backwards (3.3V comes from a switching supply that is supplied
by VFIELDB)

 (Check across the larger electrolytic capacitor
 C30 towards the bottom of the card between TB2 and TB3)

But if its not something obvious, the card should be returned
to the vendor for repair/replacement.

Is that something I can check/fix myself or should I contact the retailer. The package arrived on friday and I am fairly certain I didn't damage it.

It looks like the 7I84D has failed somehow.
There is either an issue with the 3.3V supply
or the microcontroller, because neither the
red fault or green activity LED is illuminated.

Update:

I also have a 7i73 which will later be mounted in the control unit to interface some buttons and encoders, and plugging the cat5 cable from the 7i84 to it and running mesaflash --addr 10.10.10.10 --device=ETHER --sserial
gives this:

7i97t with 7i84d connection problem

Category: Driver Boards

Thanks for your input.
 
my rj 45 plug looks like this

I have the 7i84 connected to 24V
 
on the left the calbe marked 55 is 24V an i jumpered it over so both field connectors get 24v
the cable marked 53 is ground. There are no relays or switches between the power supply and 7i84 as per the manual.

I have the 7i97 connected to 5V
 
The violet cable supplies 5V, the blue one is ground.
The 7i97 seems to work, as I am able to read the handwheel encoders I have connected.

After changing the ip to 10.10.10.10 LCNC starts with Peter's hal file, but the 7i84 still doesn't show up in halshow

Yes. the sample hal file uses a 192.168.1.121 IP address:

loadrt hm2_eth board_ip="192.168.1.121" config=" num_encoders=6 num_pwmgens=6 num_stepgens=0 sserial_port_0=00xxxxxx"


The 7I84D is not recognized.

This may be because:

1. The Ethernet cable is not EIA 568B, so the color code is
not correct for the chart in the manual
(check the RJ45 end of the cable)

2. You don't have _both_ VFIELDA and VFIELDB connected to +8 to +24V
on the 7I84

Retrofitting HURCO BMC30

Is in the works of finishing the electrical drawings of the BMC30 update.

But i would want to preserve some of the safety features.

In the current configuration a lot of the outputs are fed 24V through a relay and I would like to still have it like this.
But reading the manuals for the 7i77 and 7i71 the cards should not be provided VFIELD through a relay.

What is the danger to add a relay in the VFIELD is it the risk of contact bouncing when enabled or that the power could switch rapidly? 
Would it be acceptable to provide power through a safety relay that needs to be reset to be enabled again? (Then rapid on/off switching will not be that rapid)

Update:
Solved it by having the actuators over the same ground which a relay switches instead.

First config/error, is the 7i84 powered on?
If yes, cable wiring is wrong from 7i97T to 7i85.
-
Second config/error, is Mesa 7i97T powered on?
Is the cable connected to it?
Since network should already be set and working, then probably the wrong card IP address in the ini file.

So I just tried creating a config with pncconf again. When I don't designate any functions to the pins on the 7i84 linuxcnc will launch but not show the 7i84 in halshow.When i add a function to any 7i84 pin in pncconf linuxcnc won't start and i get this error message:
