M6 with air cilinders

I will wait you to finish this DXF import feature.

any update for this DXF import feature ?

[ivan]

We are still working on it - got sidetracked thanks to a very busy week, so the feature is not complete yet. We'll let you know as soon as it's done!

any update for this DXF import feature ?

Just wanted to let you know that we have released an update with the feature you requested. Now, in the Knife tab within the DXF Import window, you can see the 2 Axis (No Tool Lift) check mark box. Enabling it will replace the tool lift commands with M07/M08 PLC procedures. This way, you can edit M07/M08 to turn relays on and off, depending on your setup and the outputs you're using.



For the simplest setup (one relay to bring down the knife, one to lift it up) we could simply add

Code: Select all

portclr(1);
timer=500;do{timer--;}while(timer>0);
portset(2);

to M07, and similarly

Code: Select all

portclr(2);
timer=500;do{timer--;}while(timer>0);
portset(1);

to M08. This will simply turn outputs 1 and 2 on and off.

The M6 macro does not get changed automatically, so you have to use the altered macro version that you have linked earlier (http://docs.pv-automation.com/mycnc/m6_ ... pneumatics).

Unrelated to this, the visualization on the 1366V profile is currently being displayed incorrectly - if that bothers you, I'd suggest waiting a little until we fix the issue and release an updated version. This does not impact the cutting process, but the angles of the knife are currently oriented incorrectly (as of version 1.88.3661). If you simply want to test the new 2-axis feature, you can always roll back to a previous software version at your convenience: http://docs.pv-automation.com/troublesh ... back_mycnc

Let me know if this works for you, or if you have any further questions. The feature is new, so don't hesitate to reach out to us if there are any bugs to iron out.

The latest myCNC release (version 1.88.3676) also fixes the visualization, so you should be OK to update.

Hi,
Today updated to ver. 1.88.3676 to try new DXF feature and have some issues (using Thinkerboard):
1- arrow that shows tool position/direction is missing
2- somehow port3 is set when pres Start to run the g-code (old issue - I'm not sure but this happened after request of another user in the forum how to run vacuum table automaticaly at the start)
3- M7 and M8 come in g-code only for knife , pen tool has no change
--may will be better M7 portset-knife, M8 portset-pen , M9 portclr-both , similar to M62/63
--regarding the M6 (http://docs.pv-automation.com/mycnc/m6_ ... pneumatics) M62 and M63 should be removed from the macro. ??

4- there are no lift command for tangent knife min angle

1) Thank you for bringing the visualization issue to our attention - we are aware of this and will be fixing it by the next release. In the meanwhile, you can head into Settings > Config > Screen > 3D Visualization > Visualization setup and choose Tangential Knife (XYZC) - this visualization option should have the position/direction marker intact.

2) The Output #3 is a leftover from testing for that client, sorry. You can head into Settings > Config > PLC > Software PLC > __HANDLER_GCODE_START and put two forward slashes in front of the portset(3) line to fix this issue, as shown in this screenshot:



3) We have implemented those commands only for knife to test the codes so far. We'll be implementing a larger set of codes soon.

4) We will be fixing the min angle lift.

Hello,
any update for DXF feature ?

[ivan]

Hello there,

The development of that feature has been put on hold temporarily during the last few months, however we have recently started working on implementing it. We estimate that it will take roughly another two weeks until we have some sort of a working solution.

[ivan]

Good morning!

We are working through the promised changes, and have just released an update to myCNC (v1.88.4144) which adds support for 2-axis imports for creasing wheels. We have also corrected some issues with 2-axis support for knives and half-knives that arose at small turning angles.

We will let you know as we add more tools (pen, etc) to the mix.
