I would recommend reducing the "jerk" or ramp rate for the tool. Jerk is, literally, the rate of change in acceleration (or the third derivative of position)...but in general just controls how aggressively the tool takes turns. A high value, like 250 in/s/s/s will slam into corners--making the cut file run really quickly at the cost of cut quality and precision. This makes sense for somby Brian Owen, ShopBot - Handibot Forum
Yea-- What I'd really like is automated limit checking--once you home the tool, we know exactly where your hard limits are--and should be able to predict if the tool will hit one during cutting...this is on my wishlist for future software releases.by Brian Owen, ShopBot - Handibot Forum
Are you trying to just get the outline of the shape? or a 3D model of the tray? If you're just looking for an outline--I'd recommend the following: take a photo from directly above the tray, try to get high up above it and zoom in--to reduce distortion from the camera lens. Import this photo into VCarve. Draw on top of the photo using the spline tool. Once you've got the rough sby Brian Owen, ShopBot - Handibot Forum
The most common cause of z-zero inaccuracy is running out of travel either at the top of bottom of the Z axis. Topping out will shift the Z Zero down and cause the bit to cut too deeply. Bottoming out will shift the Z Zero up and cause the bit to cut above the material. How deep is your cut? Maybe if you slide the router down a bit farther in the bracket when using the shorter bit? Though there aby Brian Owen, ShopBot - Handibot Forum
To fill text inside a shape--you have to make select the vector shape in which you want to place the text before pushing the "draw text-within a vector box" button. As for vertical text...I don't have an @ symbol fonts in my software either. Though in their example the text is just rotated 90 degrees--which you could do with the rotation tool. If you want the text to be arraby Brian Owen, ShopBot - Handibot Forum
The size thing sounds like something going on in the actual design of the file--maybe the choice of "inside" vs "outside" in the profile cut that cuts out the part? Still curious about the cutting in the air issue with the test cut. You're checking that when z=0, the bit is touching the material--then when the cut is run and the z axis is driven to some negative valueby Brian Owen, ShopBot - Handibot Forum
0.92" is the total range of travel in the Z axis for the cut--though max Z depth would be a more helpful measure I agree. In the test cut, the Z first jogs to a safe height of 0.8"--then at the point in the cut where the letters are being VCarved, it reaches a depth of -0.12"--giving the range of 0.92" throughout the cut file. I'm trying to piece together why the cutby Brian Owen, ShopBot - Handibot Forum

Curtis, Try this: in your macro editor (folder icon on left side bag bar in FabMo) edit macro #3. In that macro there is a variable at the top called $x_backoff. It should be set to 0.075–change it to 0.25 and save the macro. Run the homing routine again and see if the spacing is correct. For the test cut—yes you should update the z home location. Do you have a scrap piece of wood on which youby Brian Owen, ShopBot - Handibot Forum
Yes, could you please upload an .sbp file? Also--Handibot v1.2.0--are you running FabMo on your tool or the older SB3 software? FabMo being the we browser based control system where you access the tool via wireless connection.by Brian Owen, ShopBot - Handibot Forum

That's a good point Jack--in the end, I suspect that providing multiple attach points for the router bracket has been more complication than it was worth. The idea in the design phase was that we'd need to accommodate multiple end effectors that might be very tall or very short--requiring a variety of bracket configurations. That hasn't been quite as common a need as I anticipatedby Brian Owen, ShopBot - Handibot Forum
Jack, Chordal tolerance setting is found on the first page of the configuration menu (the little gear icon on your dashboard). Jerk settings are found in the "axes" tab in the configuration menu. They are set individually for all axes. Those notes in the "final check app" may refer to things that have already been permanently fixed in the shipped version of the sby Brian Owen, ShopBot - Handibot Forum
Jack, Was just talking with our software dev about the squished buttons. Seems like it had something to do with the CSS code used to create the keypad...however, when I went to show him the error on my tablet it was fixed....I thought about it for a while and realized that I'd put the tablet on our office wifi...it went online and downloaded updates for chrome...which fixed the problemby Brian Owen, ShopBot - Handibot Forum

Jack, It's a press-in part. I added it to prevent bristles from the dust foot brush from filling up with chips (as they tend to do when they're near the vacuum port and being tugged towards the vacuum tube during long cuts). Just a couple of weeks ago one of our guys in production that runs a parts cutting tool came up with another solution--a piece of gaffer's tape applied tby Brian Owen, ShopBot - Handibot Forum
Nice work table! The Bridge Edition (Large Sheet Tool) is about as much as I'm willing to lift--and can be a bit awkward because of the size. Glad you've found a way to make it work for you. Regarding the keypad and DRO (digital position readout) being separated--The FabMo developers have been trying to get the software ready to roll out on our larger tools. On desktop size tools, peby Brian Owen, ShopBot - Handibot Forum
Just checked on mine here--yep I get the weird buttons in chrome as well. That iteration of the manual control pad is new in the 1.7.0 release of FabMo--I've shown this to the developers. In the meantime; I downloaded firefox on the tablet and the control pad works correctly in firefox. I'd recommend switching browsers for the time being.by Brian Owen, ShopBot - Handibot Forum
ohhh I see--I thought this was a separate device. Let me look into it!by Brian Owen, ShopBot - Handibot Forum
Very weird! Do you have access to alternative browsers on the Arduino pad? I'd be curious to see if firefox or some other browser would have that issue.by Brian Owen, ShopBot - Handibot Forum

I've done it with one of the 4W kits from JTech Photonics: PWM hadn't yet been implemented in FabMo so the operation was kinda clunky. It was either full on or turned off. I got a little 24 to 12W DC converter and put it on the 24V output of the handibot power supply. There is a PWM output on the control card that should be able to control the laser output but it isn't really madby Brian Owen, ShopBot - Handibot Forum

Tim, Tool changes weren't yet implemented back in V1.4.2 -- for SBP files they are available in 1.7.1 and later--but it would be best to queue up your jobs, separated by tool type in your job manager. Brianby Brian Owen, ShopBot - Handibot Forum
Tom: Sorry to see you go--I remember packing and shipping your tool! Best of luck to you in future projects. I'll see if there are any maker spaces in Ohio that might be interested. Everyone else: Tom definitely has the current "Adventure Edition" handibot.by Brian Owen, ShopBot - Handibot Forum
moretoyswins! I found one in a bin here at ShopBot! Since I only have one I'll be auctioning it off to the highest bidder, bidding starts at $90! ...Just kidding, since you've been working so hard to find one, I'll send it to you for free--just PM me where you want it sent. I know other people need these as well...so I'll keep digging for more.by Brian Owen, ShopBot - Handibot Forum
Nice work! I did some tests a while back on pcb milling where I cut thinner and thinner traces until the copper started to peel off the substrate. It definitely helped to have shallower cuts when going for the really thin traces--and shallower cuts mean a perfectly level board. But for the majority of board work it is probably true that you can cut a little deep just to be sure you removby Brian Owen, ShopBot - Handibot Forum
