You would need this and maybe another DB25 to DB25 cable, also know as parallel port cable

And might need a firmware flash, but do check what is already installed on the card using mesaflash

How can i use a 7i96s together with a 7i78 to get 2 more STEPGENs?

My main board 7i96s was being used to control 5 axis Stepgens, but one has fried completely, and i was hoping i could expand the board with a 7i78 i have laying around, to control a total of 6 (4+2) stepgens. is this possible? What bit file should I use? Is there one available for it ?


Best regards
 

There is a 7I78X2 configuration: 7c81_7i78x2d.bit 

Do you need MPG encoders or high speed encoders+index?

I have opened an issue:
github.com/LinuxCNC/linuxcnc/issues/3668

Alternatively, could someone please create a bitfile for me for 7c81 with one 7i78 and port P2 entirely for encoders (i.e. at least 3)?

Done.
Thank you.

I've never moved anything in a forum before, how do I do that?

This should be moved to the Qtvcp section.
Looks promising! Keep is updated! If you get stumped with the programming i can try to help.

Does joint.N.amp-fault-in actually turn the machine off?

Yes, it does.

Not near a machine so i can not confirm this, but IIRC:
Yes it does Disable the machine.
No, it does not trigger e-stop.

Does joint.N.amp-fault-in actually turn the machine off?

Yes, it does.

I don't know about the file size @scotta ?
But scotta made the beta to try and solve my CSS problem. I still have no solution. If you have the RT1052 controller. Let me know if you can get the CSS working on your build.

github.com/peter-pan08/LatheEasyStep LatheEasyStep is an experimental QtVCP panel for LinuxCNC that enables step-by-step conversational lathe programming directly at the machine — without external CAM software.The goal is fast, safe, and practical programming for typical workshop jobs.PurposeLatheEasyStep is designed for:

• Programming simple to medium turning operations directly at the machine
• Repetitive standard jobs (facing, contouring, grooving, drilling, threading, roughing)
• A workflow-focused approach:
  Enter parameters → Verify preview → Generate G-code

It aims to bring an industrial-style conversational workflow to LinuxCNC.Current Feature SetProgram Structure

• Program header with stock/workpiece parameters
  (diameters, lengths, units, safety values)
• Step-based program building with sortable operation list
• Save/load for single steps and full programs
• Bilingual UI (DE/EN)

Supported Operations

• Facing
• Contour
• Groove / parting-style operations
• Drilling
• Threading
• Roughing (material removal)
• Keyway (macro-based)

Preview & Visualization

• Live X/Z preview including reference geometry
• Dedicated chuck safety zone visualization (color-coded with legend)

Safety & Motion Logic (Core Focus)

• Context-aware retract/free-travel behavior per operation
• Material-aware retract decisions
• Extended chuck / no-go safety parameters:
  • Chuck size
  • Workpiece type
  • Clamping mode
  • Chuck profile
• Machine/workshop profile presets for faster setup

Project Status

• Experimental
• Actively developed
• Designed for real machine workflows
• Iterative improvements based on practical use

Known Limitations

• Not a full CAM replacement
• Complex freeform geometry is intentionally limited
• Machine-specific adaptation may be required

Target Direction

• Fast conversational programming at the machine
• Clear and understandable geometry visualization
• Safer default behavior for common turning tasks
• Continuous refinement driven by community feedback

Feedback WelcomeIf you test it, helpful reports include:

• Brief machine/configuration info
• Reproducible steps
• Expected vs. actual behavior
• Optional screenshots, preview images, or G-code snippets

 

Hi All, 
At some point the S-code could be used to command the spindle speed. The control sends an analog voltage to the LARRIOZ speed control card. The card reads a sensor that counts spindle revolutions and compares it to the commanded speed. The card can then switch relays, that in turn switch the contactors driving the motorized CVT transmission between spindle and spindle motor to increase/ decrease the spindle speed as required.
 
This never worked since I got the mill. I did at the time try to get it to work, but due to lack of knowledge and/ or documentation, I could not get working. I would think that the lithium battery in the Dallas non-volatile SRAM would be long gone, but I am not sure what would be stored in SRAM. I assume (While I know not to assume anything) that the firmware would live on the EPROM and the SRAM might hold parameters relating to the specific installation. Other than JP 1(Jumper), and P1 (Potentiometer) there is no other configuration or programming port on the LARRIOZ HABIKON1 board.
Although slow, I prefer this system, as I would not sacrifice low speed torque, as would be the case with using only a VFD for speed control.
I suppose it would be fairly easy with modern microcontrollers to get the system going again, but I would be happy to hear from others as to their experience or suggestions as to how I should proceed.
Regards
P
 

Also, how can a person do roofing, plumbing, parquet flooring, and CNC?

Multi-talented! perhaps too multi-talented!

Stop offending people, i will not warn you again!
Instead, go read through this forum, watch pictures and videos, you might get some appreciation about what our members here are capable off.

It would probably be a good idea to add MaHa's G10 solution to your startup code..
