when everything is correct, you should be able to swivel the sled and the bit
will not move.
as with everything, it’s possible to be off and still have it work well enough
for your work. Working in wood, we normally aren’t talking thousanths of an inch
for some probjects, being within a 1/2 is good enough.
so when I and others warn of possible inaccuracies, know that we are pointing
out things that may or may not matter to one person’s system.

I’ve found that single-flute stright bits have been the quietest for me.

Thanks David! Yeah within wood, my goodness usually if within a 1/32 your doing really well especially with my vision lol!! So if we’re talking thousandths…I would make it uneven just for the fact I sand everything which unintentionally would throw off by want more than thousandths. So maybe I can
Good then, not going to stress but get everything as centered as possible. I am heading down now, going to start this 2.5 hour cut FINALLY and check out he 2 router clamps. Thanks for all your help and more to come…hopefully we’ve laid this USB disconnect to
Rest once and for all!!
Darn I was at Woodcraft the other day for vac connector for the metal Maslow, totally forgot to get the single flute!! Uhg. Also if anyone asks, as they don’t tell you. When you get the metal Maslow kit it has a street elbow that comes with it to hook up vac system. The 2 1/4 inch connectors on Amazon, when reducing from 4 inch to 2 1/4 for standard vac system typically, they are loose. The 4 inch to 2 1/4 from
woodcraft, there is a thicker wall of the connector and fits perfectly! So if folks ask; that is my suggestion. I been through a bunch of different ones online and all are loose.
I am not sure if there a place on the forum you want to put this info, but here is a pic of the setup obviously the elbow is not in the mount for the sled, but you can see the nice fit AND the part number.
Morning Jon. I am starting the 2.5 hour cut now so will let you know how it goes! Same one you tried. Fingers crossed
Hey guys. I have to step away for a bit, but wanted to say this. If you set home to cut part, then load Gcode. Your part will set to the proper spot. If you move the sled AFTER gcode is loaded, then set home…or assume like earlier loaded G code then just moved to new home spot to cut…WebControl gets corrupted. I did this, even tried to reset pi…then look that green circle is back and look at my sled off to left but where the G code loaded into this item? I will swap out WebControl.json, but Jon was right there is a bug. Look at coordinates too, negative really high numbers…I had numbers like that ever time my sled got lost.
And I was using the amazon pad to move sled but load the G code directly from the Webcotnrol on pi…even cleared and tried the one I moved by WInSCP. Again I know how to fix, but clearly something is wrong right?
Hmmm, I’m not entirely sure that what you did was what causes problems with the webcontrol.json file. It might be a cause but moving the sled and resetting home is something I do a lot and it doesnt result in a webcontrol.json issue.
I’m also not entirely sure that webcontrol.json is corrupted per se. I haven’t really had time to investigate the problem. I do know that replacing it with the backup clears the errors. I also have not checked if file permissions got changed. I did do a straight text compare between my backup file and one that was “corrupted” but didnt see any differences between the two.
So maybe it’s something else? All I can pass on if it helps is that if I load a gcode file, then try to move a home after it’s loaded…my sled gets lost and it looks like center changed. Plus that second circle shows up. You can even see the values of the X and H coordinates of the sled after it gets lost…the number are way out of whack where that home point may be somewhere way off the work piece. To boot I find it odd that when this does happen, those X and Y coordinates are always big whacky values like they are compared to what the x/y home was before sled for lost.
Also what is challenging when this happens, and noticed it last time, you cannot find the last known how position to use the Go To feature and you know you could never find this point again. Take a peak at my X coordinate in the sled… -431.79. Could that even exist on this 4x8 sheet? I don’t know enough about what I am doing yet; but my guess is is can’t right??
One more thing which is odd, is i rebooted the pi and cleared the G code, loaded it back in… notice the home position off the left of center just a little…yet I NEVER changed home…yet my sled at least visually on the work piece looks to be where it is in the screen pic previously sent. But why when home is somewhere near that sled, did the Gcode load to this random slightly off center spot? It should be way left and down towards the bottom. Let’s say 2 feet left, 18 inches down. I never moved home since it was lost. I never even started the cut neither, this is just happened because I decided to move home a few inches over before setting home again and starting the cut. I am no expert by any means; but I know what I am doing is a simple task you all do, yet my sled always gets lost…but this has happened like 6 times to me now…that can’t be coincidence :)…and each time was because I didn’t set home for cut…load G code and never move the sled again (hence just pressing play)
So if this helps. I reset the pi again. The green circle just slightly left of center, when I just clicked rest how to center it moved to center. Meaning maybe I am onto not have to reset chains OR clear the .json file. The question is still why if doing the steps I was, does home thing it should be 2 inches left of center (or so) when it’s clearly somewhere NOT near that, all because I tried to move to a Home location AFTER Gcode is loaded. Sounds Like yours Jon does not do that ever; so I have to wonder why the heck mine consistently is doing this. I can be careful for
Now to NOT do what triggers this, but sounds like I should not normally have to be concerned, and sounds like to all are not having this happen
Here we go, regardless of what or why this happens all the time w/ the above issue, we are finally starting the final 2.5 hour cut :).
good luck
Thank you Jon!..so far we’re doing good, no issues. 14% complete. Now 18% complete. Paused for 30 mins while I ate, No USB disconnect so that’s great news… cutting the 2 holes with using 1pi instead of 2pi (one for monitor) changed from pinging 93-99% CPU usage to now 23-29%. That’s a HUGE difference!
All we have success!!! 2.5 hour cut completed with no issues!!! Thank you all for everything thus far! I cut over a bad area from that failed cut, but you can see all the mounting strip pockets…Maslow will eventually make one of these out of ply ! Thanks again, so excited here! image|375x500
NICE! Congratulations, all the work was worth it. Did you use the new sled?
Thank you Jon!!! 120% worth it!! I stuck with it thanks to you all!!! Nope the original sled, I was working on the metal Maslow while it was cutting. Thanks for all your guys help once again, your true gentleman and scholars! Captain Jon, Professor Orob, Dr, David Lang, and Sir Richard III. I really appreciate all your help,…seriously! Tomorrow going to get some more polishing and sanding pads, finish that aluminum up, maybe put together the Metal Maslow… I want to add the touch Z feature as my DuPont connector kit came in tonight. Once those 2 items are done and checked off, time to hit up Solidworks to reverse engineer the rest of that wall mount…then Galaga…and off to the races. Extremely excited to start designing and making some cool stuff!!!
