Yes, once you upload the g-code from the laptop directly to the webcontrol Pi, the file is saved to a lcoal directory on the webcontrol Pi. Even if you clear the gcode from the webcontrol display, the file is retained in a gcode directory for later use. You wont have to upload it again form the laptop unless you need to change the part or otherwise modify the original gcode.
Here is a screenshot of my webcontrol G-CODE menu function:
If you click on the select file box you will be presented a list of all the gcode files you have previously uploaded. From here you just need to select the file you want and it gets loaded into webcontrol.
For future reference, webcontrol stores all of your previously uploaded gcode files into the /home/pi/.WebControl/gcode directory on the webcontrol Pi.
Sorry I am back! Now I see what you are referring to, so it really never goes away when you clear the gcode. I never even questioned what the âopenâ was for. So this way works too, just load 1 by 1 to Gcode from laptop, clear right afterâŚand even if part never run before, itâs saved still. Is that correct? So I do not even need to make the part one, where you click playâŚit finishesâŚand then stores. Just load, clear on to the next one? If so this is great and now I understand why you are saying to just do it this way
When you upload a gcode file using the webcontrol menu, two things happen:
The gcode file is copied to the /home/pi/.WebControl/gcode directory of the webcontrol Pi
The gcode file is loaded into WebControl.
You could do it the way you mentioned
You could also manualy transfer the gcode files to the webcontrol pi /home/pi/.WebControl/gcode directory using your laptop and WinSCP if you wanted. Then you could just open them with webcontrol as described previously.
Thanks Jon! Sorry been trying to do this Samba and researching, I cannot figure it out. We are just using WinSCP as I have that working no issue, or this Webcontrol feature I did not know existed. Probably the Webcontrol, i think it may even let me launch it then from the Tablet if already uploaded once, and then gcode cleared. Will try that as well. Thanks Jon for this, itâs great info!! If happen to figure out he Samba will let you all know, so that you all for your help!!
For what itâs worth, SAMBA would be a nice option to have but I think itâs not necessary beyond the learning experience. let me know when you run the next test cut. I wan tto see how things work out.
I totally agree, at this point itâs all about âwhyâ its not setting up properly and working. My 11 year old shoved me out of the way to try to figure this out, then had to go back to homework. Maybe at some point he will figure out what is going on. Regarding the cut, yes the cut which I was going to do before this 2 day sidetrack Tomorrow morning, or little later if snow rolls in like it may be is when will start (some point hopefully before 12 noon tomorrow). Absolutely will keep you posted tomorrow. How comfortable are you with starting a cut, maybe hours worth. âŚpausing overnightâŚcoming back in the morning and pressing play again. Outside of power outage, would you ever do this? if your internet diconnected too in the middle of night, would this be an issue IF in theory the sled is not moving (although in the middle of a cut and paused). Asking as maybe I can split the cut up as may have some time a little later in evening to run maybe run 30-45 mins of it.
The maslow does not depend on the Internet, and you can disconnect a browser
from webcontrol without any problem
however I would NOT leave the maslow cutting unattended. If things go wrong and
it stops with the bit in contact with wood, it can start a fire. you always want
to be in earshot so that you can tell if something goes wrong.

Thank David! Yeah I would not leave it unattended, after what happened with my bad test cuts I can TOTALLY understand why you need to be there 100% of the time. That bit gets jammed for whatever reason, bad things can happen very quick!
Thank you for this info; I may but a bit right now and pick up tomorrow. Thanks again
Is it just your test without the router or a real cut? If its the without the router test like you ran before then you are probably fine. If its a real cut then, like David said, you should not leave it un-attended.
You might get away with pausing overnight but you should record the last line of gcode it completed before the pause just in case you need to manually restart if something goes wrong. That way you can manually advance to the last completed line and start from there.
Iâve started a cut, paused it and come back many hours later to resume. While it was paused, I also disconnected the router power, then reconnected it and resumed. It worked fine for me.
Yes, good call!! This way can go to the GO TO feature. good call. Finally Jon, this is the real cut of that side panel (like 2.5 hours worth), router in place I have been on and off working on the metal maslow metic-Z. Once @Orob said no need to paint, I got to thinking how I would get rid of the deeper scratches and scuffs and what not on the mount for the Z axis itself. I have been working on sanding and polishing the aluminum the past few days (in between the responses) so looks nice and clean. Just going to work on that in the shop while it runs the part.
awesome, thanks Orob. I assume since you probably have the on/of (since you did the awesome video I used) you just unplug the router from the plug correct? Then plug in, press play again?
I actually have my router on its own light switch, so just toggle it. I think the pause button becomes the continue button so you press pause to stop and pause to resume. When you pause, taking a picture of the display screen or a screenshot with the coordinates is a great suggestion.
I have to admit, and what bothers me the most, is I can easily connect to the 1st Pi4 with Webcontrol on it running in service mode, yet the second Pi4 it wonât connect to it for Samba. Unless my kid can figure out will give up on it, but boy oâ boy that bothers me!! I mean I had the same SD card in the Pi4 I CAN SEE for Samba, and can connect to in the Pi4 which now mysteriously no Samba connection is allowed. I let Ant see if he can figure it out, but from a technical perspective this is annoying! lol
I did notice that, which I was confused when it looked like you had the on/off setup. Do you have that switch in between the setup from the Arduino and the router itself?
Samba is Windows file share. To share between rpis, nfs is better. I use that to mount a simlink between a Linux server and a rpi I had taking pictures. The pi thinks it is just another folder.
As long as the rings are the same diameter and close in weight, it should be close. The ârightâ thing would be to recalibrate, but I donât think we are talking inches of error, we are talking mmâs.
hmm interesting. I did not realize it was Windows base per say as when I tried to look up the wizard dlang mentioned, it looked very non-wondows based app. It was at super quick glance, so maybe will go back and check it out more, I have the tabs still open in my browser. thanks for this info Orob!
thanks to both of you! Yes, I have the same ring setup. In fact I emailed metal maslow to see if they had any black ring setups as only have a spare blue set. I considered moving to the linkage, but hesitated for now. So yes, both my sleds would be the same ring setup. It sounds like not worth it then to bother recalibrating or running Holey again. Is that how I am understanding this, as I did plan on having to re-do everything again from a calibration setup (which I did NOT want to do, but rather do it now then when I am into just designing and cutting). I mean I want to finish this sled as I feel comfortable now with all been through to actually swap them out, but if no need to re-calibrate if not needed TRUST ME I rather not. As sound like tomorrow I may be very successful in maslow working properlyâŚand hate to ruin all the work Iâve done this far if no need to go through all the recalibration.
Tomorrow morning, or little later if snow rolls in like it may be is when will start (some point hopefully before 12 noon tomorrow). Absolutely will keep you posted tomorrow.
