PWM with a 7i96 and 7i85

Category: General LinuxCNC Questions

First, it Looks like that configuration is for a 7I85S rather than 7I85
 and second it look like custom firmware that has a mistake
(a PWM module instantiated but no pins brought out)

A configuration including a PWMgen should have a P in the name
I can make a proper configuration in a day or so if you wish

Do you have a 7I85 or 7I85S?

Onshape CAM Studio was announced last Friday with basic 2-1/2D and 3D available now and more advanced 3D to 5th axis available in the future with an additional paid fee.

Standard CAM Studio is free for those on the Professional or higher tiers, so you'll need to fork over $2,500 per year to get access to it. Enterprise Educational users may get access to it after some period of time. Or not.

PWM with a 7i96 and 7i85

Category: General LinuxCNC Questions

I'm running a 7i96 with a 7i85 for my lathe(steppers and linear encoders) using 7i96_7i85ssdid.bit I have been using LCNC pwmgen and I'd like to switch to the Mesa pwmgen before I spend time tuning the spindle VFD pid further. (I use the stepgen.00.index-enable pin for homing)

I loadrt [HM2](DRIVER) board_ip=[HM2](ADDRESS) config="num_encoders=3 num_pwmgens=1 num_stepgens=4 sserial_port_0=00xxxx" I'm using TB3 ENC 0, ENC 1, ENC2 on the 7i85 and TB1 STEP 0, STEP 1, STEP 2, STEP 3 on the 7i96.This all works with the LCNC pwmgen driving ssr.00.out-02.

I added the mesa pwmgen and I can run the mesa pwmgen in parallel but I can't find the pwmgen signal coming out the Mesa board. 
I was expecting to see the PWM output on the TB2 STEP4 (TB2-02, TP2-03) connector but I do not see a PWM gen signal? 

7i96_7i85ssdid.pin from readhmid reports there is a PWM module in the firmware (and I can see the pwmgen pins in HALMeter and HALShow) but I can't figure out the pwm signal connector?

LCNCpins.txt doesn't show the PWM assignment either?

LatheSpindle.hal has my relevant HAL connections.

Any help would be appreciated.

Installing NoMachine Remote Desktop - Package installer issues

Category: Computers and Hardware

It seems like you made a typo, try to go first to the directory:
cd ~/Downloads
and then enter:
sudo apt install ./nomachine and press TAB so it will complete it automatically to nomachine_8.16.1_1_amd64.deb and press enter

Or just open the folder in the window manager and dubbel click the file

I'm using Sunshine as host on the LinuxCNC PC and Moonlight-qt as client, this works pretty well.
github.com/LizardByte/Sunshine/releases
github.com/moonlight-stream/moonlight-qt/releases/tag/v6.1.0

On the Windows PC I use WinSCP to easily transfer files

Thank you. I'm going to test that tomorrow.

And how can I operate the relays of the 5 Axis CNC Breakout Board.

Greetings Philip

Installing NoMachine Remote Desktop - Package installer issues

Category: Computers and Hardware

they seem to think it could be an issue with the package installer on the machine itself. I tried to follow prompts to install the .deb on command line but didnt seem to have access to the directory.
james@CNCPC:~$ sudo dpkg -i /home/james/Downloads/nomachine_8.16.1_1_amd64.deb dpkg: error: cannot access archive ‘/home/james/Downloads/nomachine_8.16.1_1_amd64.deb’: No such file or directory

I'm definitely open to alternatives that will work. I just want to make sure that I wont run into the same issue when trying to install that one. Is there a any small thing i can download (minesweeper or snake maybe) that i make sure i can actually install things?
