@madgrizzle sorry but i dont know what do you mean by that im not much of a programer, i download the WebControl from the link provided by you i think in an other chat, here is the link [https://github.com/madgrizzle/WebControl/releases/download/v0.931/webcontrol-0.931-win64-singledirectory.zip](https://github.com/madgrizzle/WebControl/releases/download/v0.931/webcontrol-0.931-win64-singledirectory.zip) THANKS ---

Thanks… seems in my rush to fix one problem, I ended up creating another. long story… just screwed up. Basically, everything released since January all seem to have upgrade problems, even the version I released to fix upgrade problems (0.931). From what I can tell, based upon my testing, 0.932 does work. Everyone needs to move to this version anyway so I can better manage release testing. Unfortunately, I think you have to manually download 0.932 as I couldn’t get the upgrade to work in 0.931 on the Windows 10 release. > **[madgrizzle/WebControl](https://github.com/madgrizzle/WebControl/releases/tag/v0.932)** > > Web-based Ground Control.

I just erase all the other versions and aparently as you said the bug is fixed, let me make some cuts and i confirm the information, just a quick question, the file that said singledirectory is for slow computers right? and the other one is for fast ones im i correct? THANKS ---

Sort of. If you use single file, it has to decompress itself into a temporary directory every time it runs. This takes forever on a slow computer (like a raspberry pi). Single directory is already decompressed so starts up faster. Personally, even if I had a fast computer, I would probably still use the single directory. The advantage of the single file version is that you can readily move it to wherever you want (e.g., desktop) and just click it and run it. ---

I’m not sure what’s going on with the v.83. When I bring it up, mine says v0.932… maybe its a page cache issue with the browser… try holding the shift key and clicking the browser’s refresh icon. You do not have to recalibrate just because you updated the software. The only time recalibration will be required is if you make a mechanical change to your machine (e.g., change from say a ring kit to a linkage kit, change distance between motors, etc.) or you change from running the stock firmware to running the holey calibration firmware. ---

> [@Fede19](#): > > whene i go to actions\>triangular calibration\>cut calibration patern, wichafter clicking on is the motors try to start, but after 5 secs of noise and no movmente it sotops Is the sled near the middle of the board? Sometimes when the chains are out of whack, this can occur. But are you able to move the sled using those arrow buttons? If you can’t, then it’s not calibration issue. What happens when you run the test motors/encoders (from action menu)? > [@Fede19](#): > > 1 and 2 and so on , tan i click on acept values and then calculate and this 2 masagees apear Can you post a screenshot of the meausrements? ---

There’s a “download diagnostics file” under action. Press it and email the file that comes out to madgrizzlemaslow at gmail dot com. There might be a setting that’s out of whack that’s causing it. ---
