Hello, I have the driver DDCSV1.1 4-axis version. If I update with pandorainstaller to the latest version of the manufacturer, do I keep all the axes?
Thank you

Yes, since both hardware and software are the same for both devices. They are locked down in software, basically. The setting is preserved.

Today I did the update with pandorainstaller, "excellent work", but I still have the problem of blocking in complex programs (I have to restart the panel again), with simple works works perfectly. I've seen on You Tube a user with the same problem, today I put a fan on the back of the panel (remove the back cover) and it seems to work well, it's strange since the DDCSV1 does not heat up at all, but with the fan I have better results.

I wish to modify the slib.nc file which comes with the latest firmware patch. Most of the config files in the /upgrade/nand/ diresctory are gibberish when opened for editing as they are not iso english, so i do not know how to read/edit them.

I wish to add a manual tool change subprogram, where:

1) the main program is paused via M0,
2) a g28 command is issued (return to home), (fusion360 automatically adds a G28 Z0. move command)
3) the tool is manually changed and then manually centred over touch-off plate,
4) the start button is pressed to unpause the program
5) the program calls the built-in probe routine (via G38 Z or via M98 ????, which is it? probe.nc is gibberish. if the probe routine is not callable then steps 4 & 5 can be reversed and the probe done manually)
6) the main nc program continues on with the new tool.

 This will work well with fusion360   :nrocks:

if this is not possible then separate nc files for each tool can be created, but that entails more set-up work and file editing.

I read in the DDCSV pdf that the controller gcode is fanuc g compatible. I'm using the fanuc -G91 post processor within fusion360, but manual tool changes are being ignored by the controller (the spindle shuts off then immediately turns back on). That seems to be an easy patch within slib.nc by at adding a M0 or M1 command (wait for operator input), or by adding a new  subprogram  with the 6 steps from above.

PS:  With some testing, the controller completety ignores M00 and M01 gcodes. This is going to be harder to implement than I realized.  Yet the pause button pauses the program, which seems to be implemented in the OS, and not the slib library.  Ill use separate files for each tool as a work around for now.

Update: A quick and manual way to do tools changes from fusion360, to post with "fanuc - with subprograms" and have "subprograms in a separate file" checked off. Each tool operation will be posted to a separate numbered nc file.

I scrap the 1st numbered file 1001.nc, (its not needed) and edit the remaining numbered files. I scrap the lines between the % and 1st title in brackets ie "(boring1)" as the controller does not  accept 0XXXX header gcode, and Fusion360 inserts tool moves at the top of the file that are redundant. All thats left is tool change and pathing gcode. (fusion360 likes to insert G43 command but the controller ignores them from what I can tell). If needed,  a M03 command is added at the top of each file,  and M05 command at the bottom before the M99 exit. I double check the z start and finish positions in each file.  Fusion 360 is good leaving the tool above the stock. I set the "probe retraction distance" to be above any stock used.

I then load each file in sequence 1002.nc,1003.nc,..,..   manually doing tool changes and probes where needed. I keep track of what tool goes with which file, and which operation has been completed. I can pause/start or restart a particular file, or even re-home if steps are lost for example.

Still, automating all of this in one file, and having the DDCS pause on M00,M01 or T# M06 gcodes would be the way to go.

Hi, when I load the parameters of the Z probe and do the backspace the coordinates do not match what they should be, I am using the last update of the manufacturer in a software error or am I doing something wrong?   :doh:

If you have time, look into editing your F360 post processor - it's actually fairly straightforward to add / remove commands etc. I'm no software engineer but managed to make my own custom post for my Newker (Chinesium) controller, starting from the generic Fanuc version provided. It's written in Javascript, apparently.

Have a look https://forums.autodesk.com/t5/fusion-360-computer-aided/editing-post-processor/td-p/6709385 There's even a tutorial showing you how to create your own post processor from scratch.

Upgraded my DDCSV2.1 to the 2018-08-26 Pandora the other day.
Main reson not to stay on old software was for me the arc errors, and a hope that the tool path plot would be somewhat useful.
Used LinuxCNC from 2008 to last summer when the computer died, and did not want to go through that again to find a new one, and wanted to keep my Gecko 540 drivers.

Copied the settings file to a USB first, turned everything off, and inserted the other USB with the upgrade.
Well, it did not went too well. Screen turned black after a while and not much more. Waited, and the a restart. Everything seems to work, DDCSV2-PANDORA down in the corner.

The problem is that a lot of arcs still cuts the wrong way.
Checked my code with https://ncviewer.com/ and nothing wrong.
Tries starting with the upgrade USB again but no difference.

Am I missing something?

Pandora is untested for DDCSV2.x so I am glad that at least the installer did it's job.
Since Pandora is basically modified original firmware, it's not very likely to fail, but I am still glad it boots fine.
About the one installer problem, does the installer display any custom graphics or is it all just black?
I unfortunately can't really help you with the arc problems, sorry!

Cheers,
Benedikt
