Hi guys,
Before to ask my questions, let me shortly described my project.
I start to rebuild my CNC with structure more rigid than all in profile. For that I machined new parts in aluminium (paint in blue in picture below). Mechanically, it is OK.
Concerning software, I use Mint 19.3 with linuxcnc 2.8.2. Mesaflash and hm2 with 5i25 folder from supplier are installed.
Like PLC I used arduino Mega + ethernet shield + relay.
Arduino allow me to control light (LED RGB), relay for pump, laser and others options.
I create pyvcp panel, configured custom_postgui.hal and write a code in python for interact with arduino through ethernet connexion. That work pretty well.
Before rebuilded my CNC I used chinese controler (A145A) and DM542 drivers for control my steppers motors.
For increasing accuracy I add linear encoders (X, Y1 and Y2) and then buy Mesa 6i25 and 7i77 for control all.
But it seems that I make a confusion between servo and stepper.
Then I cannot used my 7i77 for control stepper.
Can you confirm my mistake?
Can I used my chinese controller connected to P3 of 6i25 (P2 will used for 7i77)? or buying 7i76 is unavoidable.
If yes, which .bit I can flash?
When I load PNCconf it seems that linuxcnc don't recognize my 6i25 card.
As you can see there are not card specified after "Mesa0 PCI/ETH0/Parport Card:" It is normal?
below my actual configuration flash on mesa 6i25:
