I tried these. Anyone else? I need to do them again in better quality ply to confirm my observations, I used low quality stuff while ferreting out other issues. The main thing I noticed is the fit side to side on the puzzle fit index parts pinches giving a bit of deflection. A little sanding seems to do the trick though. The fit on the 0 fence is a bit loose though. Those are side to side, butby Marc - Handibot Forum
I was under the impression 1" per second was slow. Completely agreed on setup, and after working through this I don't know that I'll ever try to go above 1" per sec again. tl;dr this is all my fault from using an improper bit. At David's advice I checked the machine over for loose bolts. I found some loose, particularly on the Z anti backlash nut. I had found a looby Marc - Handibot Forum
I've been using a pass depth of .2". What speed are you running at? I'm set at 1" per second which seemed slow from what else I've read here, maybe it's still not slow enough. Ii'm working with average cabinet grade plywood right now.by Marc - Handibot Forum
Thanks, that will be more efficient. We'll report back here after we chat tomorrow.by Marc - Handibot Forum
Travel, then Christmas kept me away since my last posts. I have a simple job requiring tiling so I went to go cutout the fences that were posted earlier this month. I wasted a lot of ply on this. I rediscovered that the settings for the tool paths aren't seemingly honored, and reset the default to match what I was trying to set from VCarve. Still, the errors were consistent. The tnut hole loby Marc - Handibot Forum
Yeah, looks like it slipped a bit. On the Y I'm off by 1/16th, on the X more like 3/16th. That makes sense as I had a better guide on Y. In retrospect I would have done more setup on how to position fences to move the bot along to cut this. Did you cut your base using a HandiBot or a larger machine? Curious if you've got guidance on getting the base cut using the HandiBot itself beforeby Marc - Handibot Forum
OK, it didn't work out. Bill, I think the problem that bit me will impact your files as well as I only changed the outside line. The issue is the pocket lines are the correct dimensions, but the pocket as cut is on the inside of the line. The full pocket isn't cut so just enough is lost that the bot doesn't fit into the recess. Maybe the pocket should be raster instead of offset?by Marc - Handibot Forum
I measured these and sure enough it does look like the shoulder of the rabbit is about .05 deeper than it should be. The edges might be off a tad from repositioning the bot and the work piece, but I can't trust that as I unthinkingly sanded them. I went and grabbed some straight router bits to give this another go.by Marc - Handibot Forum
I think this is great. I see I was misinterpreting in my head how some of the fence guides mounted. It's probably time to start moving to example photos of how these mount and are used though. I ever only get a glance in the YouTube demos of what's happening with the bases, then it's gone. A YouTube demo of the jig rather than a focus on the tool would probably be fine though.

The new base doesn't match the fence inserts posted earlier does it? Also, I measured my HandiBot base and it either doesn't fit or there is something about the pocket cuts I'm not understanding. The side protrusions measure 7.823" or so in VCarve, but measuring my base I'm getting 7.25". That seems like a lot of play there. The measure between the side protrusionby Marc - Handibot Forum
OK, I knew I had loaded the provided settings but when I went into setup it says I selected a PRS Desktop. I just reloaded and it still says that. It says the bed size is X 6.5, Y 8.5 and Z 5. It also has the Z zeroing plate selected. The values for the prox switches are at .5 instead of .05.X can get to 6 with that, Y can't get to 8. With your adjustments I can now get to Y 8.

Coming from 3D printing I'm accustomed to all of these settings occurring in the slicing software, the settings in the control host are used for manual control but not in the job you run. As such I haven't been paying enough attention to the shopbot host software. Interactions between the spb file from VCarve and the host software are still an are I need to learn more about.

Awesome! Thank you! I may try some of these this weekend, yes I'll measure first. For the fence inserts, is the idea that you would extend those to meet the piece you are positioning under the bot? Basically make a set of fences for different sizes of lumber, or are you adding clamps or holding material elsewhere attached to those outside of the cutting area?by Marc - Handibot Forum
Looking forward to it. Ran to check git, but guess I'll have to wait a little longer. :-)by Marc - Handibot Forum
So I just discovered the Vectric projects. The Cool Cubes one looked like fun so I gave it a try. I'll comment that I really like the way these files are setup using layers. There are a lot of good practices to learn from these, like marking hold downs and indexing positions. Obviously it won't fit the HandiBot build area. I moved things around so that they were on tiles sized toby Marc - Handibot Forum
I drilled through the HandiBot base holes with a 1/4 bit into a base board. I then inserted 1/4 dowels into these to be able to remove the bot and reposition it in the same spot. I setup a second set of indexed holes 8 inches up, but as we'll see that isn't going to work. Next I added a spoiler board onto this base. Not really necessary here, but I'm thinking about how to evenby Marc - Handibot Forum
Thanks David, I'll try the prox advice tomorrow and see if that fixes it. The X/Y home is me not thinking things though. I was comparing a drilled hole at "0" to the bit position. Of course only the edges of that hole were at 0, not the hole. I'd use the brick wall smiley, but it isn't here. With this subject matter I think we all need it. That and the dead banana.

Wow, thanks guys. Great advice. I clearly need to dedicate some time to just figuring this stuff out without a project in mind. Just test materials.by Marc - Handibot Forum
Nice work. I need to give up on indexing for a bit and move to sheet goods like this. I just spent the day setting up files for a job, made an indexed base and discovered something. X is 6". The Y envelope is not 8". The Y axis is slightly over 7 1/2". It will try to go to 8", bump, and since there is no feedback the remainder of the job will be ruined. Lovely.

Thanks. Yeah, agreed on routing the face. I had it on edge in the picture checking how high I could get it. I have a project in mind for 4x4 lumber I didn't have on hand. I think I'm wrong about the base being to thick as well. What I forgot was I can raise the pieces back up higher using the backer board. So I think I'll try this again, but incorporate the backer board as partby Marc - Handibot Forum
I suspected that was the answer. It'd probably still be helpful to us to see those designs and use them as starting points rather than going from scratch.by Marc - Handibot Forum
I have the router set to it's slowest setting, which per the manual with it is 16000 RPM. All other speeds were higher than anything I saw in the existing tools database in Vectric so I decided it made since to put it there and leave it. Shouldn't be slow speed with the PC. I'm using a USB3 port on a laptop that has an I7, an SSD and a 16GB of ram.by Marc - Handibot Forum
Thanks for sharing that. I don't follow Blender very closely, but I'm going to have to check this out.by Marc - Handibot Forum
I'd really like to figure out how to make a decent jig for clamping framing lumber consistently and square under this device. With that there would be a lot of great experiments to do in joinery. Such a jig exists in the demos that sold the machine to many of us. For some reason ShopBot won't share that with us, so we're on our own. As such I'm sharing my first failed experby Marc - Handibot Forum
I asked for the files that correspond to the jigs in all of the videos you posted promoting this device for your KickStarter. I don't think that's unreasonable. Those jigs featured prominently in all of your materials. Why are you not releasing them? I appreciate the engineering drawings for making our own jigs, but I'd rather have a known good jig to start from. I'm especiby Marc - Handibot Forum
I forgot to come back and update. Yes, slowed down to 2 and it cut well. 2 on some 2x4s was too fast though, had to go shallower and slower. Backed it all the way down to 1. Still need more experimentation.by Marc - Handibot Forum
So offline conversation is my speeds were too fast. I copied a similar upcut bit, but it was defined for a bigger machine. I missed David's comment in the other thread that speed shouldn't be above 2" per second. The settings I copied were 6. Turns out that can impact dimension. I haven't had a chance to rerun a cut file. Somehow the last four nights have all been booked, andby Marc - Handibot Forum
Almost every video of the Handibot in use featured a specialized base of some kind. Can you guys post the files for those? Or at least the theory regarding them. In particular for beams it seemed to me the bases were made to position and possibly clamp the beam to a known relative location to the tool. When doing that is the idea that you then put the drawing for what you are cutting in the beamby Marc - Handibot Forum
No, the handibot and the wood did not move. The dimensions are way, way off for what it is cutting. Movement would not account for it. And yeah, the wood is rough scrap play to learn with. I just need to get some good straight cuts and I'm going to move on to nice stock. I was shocked at how well the first engraving went.

The z bump method is great, thanks for sharing. I don't understand how the recommended way is supposed to work at all. I tried it, but uhm, the machine is resting on the material. How is the paper supposed to move?by Marc - Handibot Forum
