Re: Absolute Max Temp for PCB heatbeds? - 7 years ago
Thanks all, and apologies for the lack of followup. Based on the suggestions (and the fact that i couldn't figure a way to mount it) I'm going with silicon heaters on the back of some 6mm aluminium plate. It's complete overkill, but it should work pretty well and gives me an excuse for some more packages arrivingby jebk - General
Absolute Max Temp for PCB heatbeds? - 7 years ago
Has anyone ever experimented with the max temp it's feasible to get a PCB Heatbed up to? My wife has a vinyl cutter she uses to (amongst other things) make tshirt prints. It's very small scale so to date she's been applying with an iron. The problem is the inconsistent pressure/temperature application sometimes causes issues. Being a bit of a geek the garage is filled with half finished printerby jebk - General
Re: Precision Piezo Z-probe Now available. - 7 years ago
SupraGuy, i'm testing out moriquendi's new part on a similarly sized bed with a 3 point mounting setup. I'm mounting under the bedsprings and it works pretty well. Although the whole thing is in bits at the moment so it's not had a tonne of testing, it does do a decent job across the whole bed.by jebk - General
Re: Lulzbot Taz6 Homing Crash - 7 years ago
Have you updated the firmware? Are you sure you're using the right gcode? I'm not familiar with that printer but on my Frankenstein with a nozzle sensor the process is G28 XY then G29 Z0 to home.by jebk - General

QuoteFA-MAS Just curious, what material are the plastic parts that are provided in the kits made from? The site says ABS, although I printed one in PETG and it works although I don't use it anymore.by jebk - General
Re: Precision Piezo Z-probe Now available. - 7 years ago
QuoteChowa I have the under bed piezo mounted at the x intersection of the bed carriage. Printer is the black widow piezo is 20mm with the plunger type. I'm not sure I can picture that. You mean it's mounted on the cross piece supporting the bit of extrusion the carriage runs on? Interesting you get flex there, but unfortunately mine is a more traditional i3 style (2linear rods)by jebk - General
Re: Precision Piezo Z-probe Now available. - 7 years ago
Apologies if this is answered before, but what's the current thinking on under bed mounts? I'm now putting piezo on my 3rd machine a wanhao i3 (already on my x5s and a kossel mini). I don't want to do a lot with the carriage as I have a titan aero mount i really like on there. Are leadinglights simple mounts working for people (https://www.thingiverse.com/thing:2580078) I only see 1 make or shby jebk - General
Re: Precision Piezo Z-probe Now available. - 8 years ago
QuoteCaptainHero Took off the motor and the filament guide part and this is how it looks. I guess technically i may be able to put the sensor somewhere at the black backplate that holds the extruder setup to the x carriage but its quite sturdy setup so i am not sure what good that would do since i don't think the motor would press against the sensor at all when the nozzle touches the plate.

Re: Precision Piezo Z-probe Now available. - 8 years ago
I can't speak to direct use, but in principle my answers below: 1 probably not hugely. Certainly functionality would be higher on the list. 2 as far as possible I'd suggest you don't exceed the heatsink diameter in at least one direction. Most mounts (for non deltas) would let you go as far as you like 'forward' but not very far back. 3 I'd say this depends on the market you're aiming at. The bulby jebk - General

QuoteDjDemonD Good work. In terms of testing probe accuracy I'd just run G30 S-1 (not sure the equivlanent in Smoothie but this reports the distance travelled) and repeat it 20 times, then put values into a spreadsheet and get range and deviation. So, in terms of accuracy (this is from z=10): 10.415 10.4187 10.42 10.4213 10.4187 10.4175 10.4225 10.425 10.425 10.4362 10.425 10.4263 10.4237 10.43by jebk - General
Re: Precision Piezo Z-probe Now available. - 8 years ago
QuoteDjDemonD I know basically how to get a probe working in Smoothieware, but I didn't get as far as grid levelling. I'm not sure there is a built in probe accuracy test, but you can send G30 and just record 10-20 values and stick them in a spreadsheet. Thanks, these are my first set of tests: 0.0375 0.5225 0.7913 0.9713 1.2288 1.5050 0.0738 0.6175 0.7388 0.8750 1.0588 1.2800 1.5150 -0.8737 0.69by jebk - General
Re: Precision Piezo Z-probe Now available. - 8 years ago
Finally at a stage where this is ready for testing in anger now (I changed to just a mount rather than a whole carriage, as all that was doing was making things more complex). Unfortunately I'm using Smoothieware to control the machine, not RepRapFirmware. I can see how to set it up to probe (and have done some tests with a microswitch & finger combo whilst I wait for my final draft to priby jebk - General
Re: Precision Piezo Z-probe Now available. - 8 years ago
QuoteDjDemonD I can send you more Piezos if you need them, sounds promising. Thanks for the offer, but I already have a batch on order that should be here before I get chance to work on it properly again anyway.by jebk - General
Re: Precision Piezo Z-probe Now available. - 8 years ago
Just to come back to this. I'm presently iterating on this design, which should work as a replacement carriage for any of the 2020 extrusion based printers (Mine is going on a TronXY X5S, but I can't see anyreason it wouldn't work on a CR10 etc.) So far I have what appears to be reasonable repeatability (I'm testing in a jerry-rigged dremel press as I need the printer working) but have some worby jebk - General
Re: Precision Piezo Z-probe Now available. - 8 years ago
Sorry yes, I'm not making myself super clear I realise. The piezo20 type screw/groovemount won't work with the 20mm sensor I have, and scaling to fit will probably take up more space than I want to use. The plan was to build something similar to the titan mount but just as a flat plate with the hotend mounted to the front, however I assume that might need some work to get the right amount of defby jebk - General
Re: Precision Piezo Z-probe Now available. - 8 years ago
QuoteDjDemonD So you are planning to use a titan/aero bracket like this one? No, I'm using a Bowden setup on Tronxy X5S (cheap corexy from china) mount is similar to a CR10. It's probably more straightforward to just get a 20mm sensor and use the groovemount, but I'm a sadist. Just wondering if you've found a way to temporarily mount the sensors for testing rather than supergluing.by jebk - General
Re: Precision Piezo Z-probe Now available. - 8 years ago
Hello! My kit arrived yesterday, and like a lemon I didn't realise you don't have a part for the 27mm piezo with a groovemount. Not a problem making one up, but i wondered if you had come up with a non destructive way to mount/remove the sensor for testing when using something like the titan aero mount?by jebk - General
