UCCNC/parallel module hardware installation

Hi Hassa,

The process is exactly as you suggest - just unplug the USB board and replace it with the parallel interface board. Obviously the power should be OFF!!

Plug in your UC100 module and the USB link to the PC running UCCNC. With power applied to the PC, the green light will indicate power to the UC100 via the USB cable. Both lights on the UC100 should be on once the UCCNC is running with the proper driver in place (and the license file recognised).

Hey peter,

thanks for the confirmation of the installation.
Ive managed to swap over the card and installed the software without much trouble! (very happy cause that doesnt often happen)

I have also got the tool length sensor and have done the installation and software setup as shown on the website.
There seems to be no connection with the switch and the machine.

when i check the diagnostics tab to see if the green light shows up,nothing happens.

really have no idea why its not working. Any ideas?

thanks

I believe on the latest set-up of the sets, there is a jumper on the main board which needs to be removed in order yo get the sensor working.

hi guys,

got the probe working. but not completely. now the software doesn't calculate the proper zero after probing.

it just goes back to my first zero point after doing the zero point probe.

really am new to this so no clue as to whats causing it or even how to run it properly.

- Have changed the macro file.
- Have tried the active low preference on the I/O setup

Followed the steps according to the instruction on the stepcraft website to the point and no luck.

any help would be great and ive only got 3 more days to fix it up.

thanks
hassa

Hi,

I assume you are not using an automatic tool changer, but will be changing tools manually and then placing the tool length sensor on the workpiece before starting the probe macro from the run screen of UCCNC. You will of course have to manually position the tool above the sensor using XY jogging befoer starting the probing sequence. I suspect the M31 macro you are using is for the tool changer option, not for the manual alternative.

When the macro lowers the Z-axis, it normally expects the sensor to open circuit when touched by the tool. At this point the Z position is preset to the actual height of the sensor above the work surface. You will have had to enter this value into the macro prior to probing as the parameter "double newZ" in the first few lines of my macro shown below.

//M31 probing macro
double Zmin = -100; // Max.Z depth
double FeedrateFast = 300; // Fast feedrate for probing
double FeedrateSlow = 20; // Slow feedrate for probing
double SafeZ = 100;
double retractheight = 10; // Retract height
double retractforsecondmeasurement = .5;
double newZ = 32.60; // The new Z DRO value after probing and calibration (NOTE - THIS IS THE HEIGHT OF MY SENSOR, NOT YOURS ! ! ! ! !)

Initially this value should be set to a value a couple of mm or so less than the measured height of the sensor. After probing and executing a "Go to zero" the tool should be just above the workpiece surface at this point. Jog Z axis SLOWLY down until the tool touches the workpiece and note the Z ais DRO reading. Add this to the initial value you entered as "newZ" and the setup should be complete.

Good luck

Peter

Hey Peter,

Thanks so much for the info.
It works now.

Im so glad this forum is around and for the help people offer.

Much appreciated.

Thanks
Hassa
