correspondence of unused i/o pins to physical connector location? was created by pgf

correspondence of unused i/o pins to physical connector location?

Category: PnCConf Wizard

Is there a chart somewhere that correlates the 3 digit I/O number shown in pncconf with their physical terminal on the board?  I assume those 3 digit numbers are a number used by the firmware to represent the pin, but on the board, by the time you try and subtract out the power and ground pins, and try and figure out how many actual I/O pins an encoder or serial port uses, it's almost impossible to tell what's being configured.  I've been trying to compare with the board drawing from the Mesa 7i96 manual, and also with the actual board, and I'm coming up empty.

I'm referring to the 023 to 032 numbers in this screenshot.

PCIe - No parport registered at "0x " . This is not Always an error.Continuing.

Category: Advanced Configuration

Running
sudo lspci -vnn

Give both the name of the card name & PCI ID

Here's one that might you lead you astray
6:0d.0 Serial controller [0700]: WCH.CN CH352 PCI Serial and Parallel Port Controller [4348:5053] (rev 10) (prog-if 02 [16550])
	Subsystem: WCH.CN CH352 PCI Serial and Parallel Port Controller [4348:5053]
	Flags: medium devsel, IRQ 22, IOMMU group 19
	I/O ports at 3008 [size=8]
	I/O ports at 3000 [size=8]
	Kernel driver in use: parport_serial
	Kernel modules: parport_serial

Looking through /proc/ioports shows the serial port @3008 and the parallel port @3000

dmesg shows
0000:06:0d.0: ttyS4 at I/O 0x3008 (irq = 22, base_baud = 115200) is a 16550A
parport0: PC-style at 0x3000, irq 22 [PCSPP,TRISTATE]

Then there's info under /proc/sys/dev/parport/parport0 (in the case of the first parallel port) the hal_parport gets it's info from and depending on what is found there, gives the message that started this all.

Just saying there seems to be a couple of ways to skin the cats.

A photo would be nice. If I pull the quill in my top slide forward, it would break the hydraulic pipe at the rear elbow. It would be nice to see how your one allows movement. It's too blurry in your photo.
Before you remove the hydraulic ram you have to remove the screw in the clasp claws and unscrew the claw assembly. The when the hydraulic ram is removed all the springs come out with the ram. Maybe you draw rod is broken?
Cheers,
David

Yes and mine has the hand adjuster on the top slide same as the one in the photo
Makes it easy to adjust the Z spindle.
My phone camera is damaged. I have to replace it so I can send you some images

Indeed, I just tried it and I got the same result. I think this is an out of the box problem with these drives. I have a batch of 7 drives all having the same issue, while before they never had this issue.
I also checked, all the settings/parameters are the same with the working and not working drives. After opening them up, also internally they look the same.

I did recall you said you would be away.
I'll have a quick try on mine by simply loosening that clamp bolt. I didn't realize before that is all it takes.
With the hydraulic pipe elbow removed the assembly should come out whole.
Then the only tricky part was warming the thread on the hydraulic ram so the Locktite came free.

Hi,
for your information, I had the same issue.
I am currently debugging and check if it will work. I can then update you :)
Could also not compile it myself due to dependencies issues.

Hello David
Yes I have had the spindle our several times and lubricated the bearings with the special Kluber grease. The hydraulic unit comes off no problem but I cant get to the spring washers
On mine the very long drilling to the sight tube was clogged and it took a lot of rodding out to fix. It's hard to read through the sight hole
I will check this out. Thankyou
Cheers Chris .

Hi David
Sorry I have been away for a few days
Thanks for the photo and the description of the Z hydraulic pipe work .Now I am back on the job. I am reluctant to dismantle the Z hydraulic spring loaded tool gripper as I simply don't know what I am doing and risk damage to the unit. I will have another look tomorrow. I can remove and adjust the gripper but I cant get to see the spring washers and they could be the problem. Further the Z tool changer worked before I renewed the spindle grease so it has to be something I have done.
Cheers and thanks for your interest

@RotarySMP could I maybe ask you a few questions about your retrofit?

 

I would recommend you start a new thread for your 400E conversion. If you ask your questions in an unrelated thread like this, or my long 400E conversion thread, the answers become very hard for others to find.

Parport bob is easy to use.
There are guides to set it up.

If it is a gantry machine then it needs to be homed before you can manually jog the Y axis.

2.9.3 - Stuck in wrong state and stops

Category: Plasmac

Interestingly if I unlink haul.program.is-paused in a sim I see similar behaviour:
[b]Actions on the simulator:[/b]
Homed the machine and enabled the torch
Started a job
While the thing was moving to start the cut, I set the ohmic volts right up
When it tried to do the ohmic sensing it failed with the message "pierce height would exceed Z axis maximum limit". This stopped the machine
Pressed the pulse button. The button shows the countdown timer, but the torch does not fire
I cannot get it to fire by activating the float switch though.
