M400S Rescue (All Issues Solved, Up and Running)

[AcornJosh]

Cost for CNC10 hard drive is $425 list. We can build V2.36 and V2.72 easily with compact flash in an IDE reader. I can build some versions in between but 2.72 and 2.36 seem to be the most common.
I also have v2.73 on open suse 11.2 on a 250gb SATA SSD for the more modern motherboards. Same $425 price.

Thanks Josh,
Replacement motherboard ordered and I ordered a new SSD with latest version of CNC software for CPU10
Hopefully that resolves the oddities.
I installed a floppy drive to the floppy connector on the motherboard to try and get a report, booted the PC, floppy was scanned but the Linux software would not recognize the floppy. Hearing that the early versions of Centroid CNC Linux was finicky about USB drives, I grabbed a handful and got ONE to work and I was able to get a report. It is attached here for reference.

Linux...blech, kaka!

I am about to wrap this project up. Need a last bit of assistance with the control
CPU10 control, running Linux.
When the control boots up, there is a Low Lube message. I cycle the Estop and it goes away.
I have checked the low lube contacts in the pump. If I switch them, I get the alarm and can not cycle the Estop to get out of the alarm.
This one I can't figure out. Marc maybe you can take a look at the report and provide some insight.

Don't understand why the Low Lube message even shows up.

What type of lube pump is it? Parameter 179 controls action if defined in plc src.

179 – Lube Pump Operation
This parameter can be configured to control a variety of lube pumps. The value is formatted as MMMSS, MMM for
minutes and SS for seconds. Below is a table of some examples.
Type of Pump MMM SS Operation
Mechanical/CAM 0 0 179=0 Power is on when machine is running a job or in MDI Mode
Electronic “lube first” 16 00 179=1600 Holds power on to the pump for 16 minutes of job or
MDI time
Electronic “lube last” 16 00 179=1600 Holds power on to the pump for 16 minutes of job or
MDI time
Direct Controlled
Pump
30 15 179=3015 Waits for 30 min of job or MDI time, then applies power
for 15 seconds.
Parameters.

Thanks Ron. That's not the issue. Getting a low lube notice on system start up that goes away when Estop is cycled. Pump is full.

You have bit 0 of Parameter 178 set (value +1), which tells the PLC program to assume a normally-open low-lube signal (closes when the level is low, instead of the normal open-when-low behavior). Parameter 178 was used in this way before the lower-level input inversion became available with CNC11/MPU11.

My guess is that, on startup, the correct value of P178 is not immediately available to the PLC program, and so, since INP18 is open, the PLC program latches a low-lube fault. Then, once it gets Parameter 178, it sees that the low-lube condition has gone away, so you can clear the latched fault with emergency stop.

Try reversing the float switch, and also changing Parameter 178 from 129 to 128.

Thanks Marc!
That took care of it....
