Ok, not sure how I do that as I used the stepconf wizard to create the config files and it created the pyvcp files.

Gmoccapy provides it's own pins for spindle feedback which you can connect in your postgui halfile:

Hi Grotius,
In the latest version of scurve, how do you set the max deviation parameter? 
Right now, I am not able to change the filleting using the spline. Is there any way to enable spline filleting?
I am running the ../cmake/configs/axis_9/axis_scurve_9_mm.ini config.
My tpmod parameters are: 
Parameters:
Owner   Type  Dir                 Value  Name
     4  float RW                    0.5  tpmod.hal_blend_speed
     4  s32   RW                      1  tpmod.hal_blend_type
     4  s32   RW                      1  tpmod.hal_g0_transition_blend
     4  s32   RW                     20  tpmod.hal_look_ahead_lines
     4  float RW                   2500  tpmod.hal_max_jerk

No amount of fiddling with G64 is getting the splines to show up.
Am I missing something or some step?

did you tune your servos?
could be just small gain in drive.

And will go with two THCAD-2 as ohmic sensor looks like very good approach. For the moment i'll stick to the hand held Duramax torch i have. 

Thank you so much for the data, that made my day!

as soon i have the hardware i will try to get it running. If i have time in the i will try to make a GladeVCP screen for the turret.




Greetings

The thcad2 replaces both the thcad 10 and thcad 5. The manual will tell you how to configure it. Go for a 200 volt range and you will be sweet for the 45XP

Personally, I would buy the cpc interface. There is a trick you can do with a short piece of fine wire inserted into the torch connector to permit CNC firing of the machine torch Search for it.

Thank you rodw.

I don't have THCAD yet and i just saw on Mesa website only THCAD-2 is available:( The rest is out of stock - looks like i'll have to go with THCAD-2 anyway and deal with voltage dividing somehow. My Hypertherm 45 XP is not equipped with CPC apparently, the second source as well. Buying CPC now is not and option so i will need to look at THCAD-2 if i can add some resistors to extend the range.

I'll spit my dummy if you delete this topic. I learnt stuff that was interesting. I had no idea about the whole silicon thing, which was largely due to living in a western English speaking country.....and probably dropping out of highschool. My attitude was inversely proportional to my intelligence. The more I learnt the bigger cnut I was at school.
School is wasted on the young

If you had of read the docs, the parts regarding using a parallel port and software step generation, you would have learnt that there is a limit to the stepper speed based on the latency of the base thread.
This is the problem, people don't fully research/read the docs and don't fully understand what they are doing. They also assume things that are not so.
Many times people blame Linuxcnc, 99% of the time it is a mistake they have made.
The recent rise in the availability of home CNC machines has led people to think it is easy thing to setup and use. It's not, there are many hats you have to wear. And to be fair the basis for a project for Linuxcnc, all those years ago, was for control of industrial machines. I don't think the original authors of the papers imagined the extent that small CNC machines would become available to the "average Joe".
Checkout the mesa website, see what they have available. Read the forums, see what other people are doing. Checkout the remora project, have a look at Linuxcnc-RIO, geesh I even gave a link to my own GitHub project.

Is there any information on which pins on 7i76 board are the pwm generators mapped onto? For instance, TB2 connector on 7i76 had GND, Step0-, step0+, Dir0-, Dir0+ and +5Vp with default stepgen firmware.
I couldn't find which pin to connect.

I'm sorry if my previous post was hard to understand or based on misread info. 

I was under the assumption that the most affordable mesa card for 6 axis (5 move and 1 extr) was around 200 bucks. But you are totally right better to ask than assume... I'm sorry for sounding stupid.

I'm still very much open to guidance for hardware selection for my 5 axis printer

Have a great day!

Hello. I started making my own GUI little by little. When creating a Stacked Widget, I add buttons to switch between pages. I did it according to the instructions: added PushButton->added Dynamic Property->Name: change_page - stackedWidget Index-1. I press Ctrl R and nothing happens.
 
 When you click on the button to go to another page, nothing happens in preview mode (Ctrl+R). And if I launch the GUI via lcnc, then when I press the button I get an error:

If it is just for testing, you can just set up the network interface in the virtual machine.

You can add me on discord, my username is onceloved.cn I can use TeamViewer to remotely configure for you

My graph in the plasma primer in the linuxcnc docs is the only real data I have seen about volts over distance.
linuxcnc.org/docs/stable/html/plasma/plasma-cnc-primer.html
It showed for the specific machine, it was 7.53 volts per mm with 99.4% confidence over 16000 readings. So a 2 volt range is a good target to get your 0.01" which is realistic
You voltage will be around 130-150 volts when cutting. I have run a 300 v full scale and also 170 to 200v an I never saw any difference. I would just use your thcad 300, seeing you have it, set it to 1/32 frequency and make some parts.
