Whenever I receive email notifications the url seems to have a stray semicolon at the end. See attached pic. Clicking on it takes me to the start of the topic and I have to manually edit the url to get to the correct message. It only does this on my tablet. Works fine on a PC.

+1 for your hole-punching method. I had similar problems and solved it with a punch used to render cd/dvd discs unreadableby tekkydave - General

It's been a while since I did any Marlin config but I think you need to enable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PINby tekkydave - General

Try loosening the 4 screws in the mount a half-turn at a time. If they are too tight there is no flex in the system which is required.by tekkydave - General

I bought an Andromeda with a view to integrating it into my D-Bot Titan Aero set-up. I haven't worked it out yet but there is definitely room to *carefully* drill out the 3mm center hole to 4 or even 5mm.by tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
I don't know if anyone else has discovered this but I thought I would share it. I wanted to drill a 27mm piezo but was nervous about drilling it. I remembered I have a cd-punch, the type used for making CD/DVDs unreadable. It works quite well (see attached images). The hole is about 5.8mm diameter with minimal distortion of the disc.by tekkydave - General

Re: Precision Piezo Z-probe Now available. - 6 years ago
QuoteMoriquendi I think, but I'm not sure, that in marlin a positive offset will increase the distance between the nozzle and the bed. If you do a series of G30 probes do you get consistent results? Idris My understanding is: A higher negative number will make it go closer to the bed. A lower negative number will make it go further away from the bed. Hope that's right.by tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
Yes, you are correct. When I was using RAMPS & Marlin I always used the Mesh Bed Levelling. The Duet/RRF Mesh compensation is very similar to Marlin's Mesh Bed Levelling. My bed is 300x300x6mm cast aluminium with 3mm borosilicate glass on top. It is almost flat and only needs probing in the 4 corners. Any more than that would be overkill I think. I tend to use babystepping to adjust the finalby tekkydave - General

I run the following via a macro ONCE after I turn the printer on: T0 ; Select Tool 0 M104 S130 ; Set Tool 0 temperature to 130 - no wait M190 S60 ; Set Bed temperature to 60 - wait M106 P1 S0.75 ; Hotend Fan to 75% (reduce vibration for probing) M290 R0 S0 ; Clear Baby-stepping G28 ; Home All Axes G29 S2 ; Clear Mesh Compensation Values G29 ; Run Mesh Cby tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
I use a Duet WiFi which runs the RepRapFirmware (RRF). The G29 behaviour is different for RRF to Marlin. I run the bed mesh levelling once at the start of each session. This stores the levelling map on the SD card. Then I just run G29 S1 in the slicer start gcode to load it at the start of each print. The fan only has to be reduced during the G28 homing which takes seconds. I'm not sure if Marlinby tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
QuoteYMita QuoteDjDemonD One solution depending on your controller might be to use a controllable fan output for hotend fan and then you can turn the fan off during probing. If you are probing cold or at an intermediate temperature such as 130 deg the heat creep (depending on your hotend) should be little or no problem. Mr.Simon, thank you good advice! But I'm using UBL system on Marlin, and itby tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
G30 will start the probe from wherever you (manually) set the nozzle. If you can, manually set it to 100mm as suggested, then try the G30. You should have plenty of time/space to tap it and check it stops.by tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
I have used both the PP20 and Orion now and can definitely recommend the Orion. I had issues with the initial groovemount supplied with the Orion as it was a bit loose in the Titan. This was speedily rectified by Idris with an updated STL. It is now nice and snug.by tekkydave - General

QuoteMoriquendi QuoteValSimDim "Given that one of our primary selling points is the accuracy of the system I'm somewhat nervous about releasing the PCB to be included in printed parts that may not match what we produce."

Re: Precision Piezo Z-probe Now available. - 6 years ago
After testing the V2 groove-mount on my printer I discovered that having things screwed up too tight causes issues. Using the supplied groove-mount top and having the 4 screws quite tight it worked fine. I think this was due to the looseness of the top in the Titan. When I fitted the V2 there is no looseness at the Titan so having the screws up tight caused it to crash into the bed. This was deby tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
Hmm, looking at the one supplied with mine it is very thin in the neck. Measuring the CAD files from Thingiverse it is about 1.75mm. Measuring the V2 one I tested yesterday gives 1.95mm. It feels stronger too.by tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
It is very firm now. I dont think it would go any bigger. Thanks for the new design. Daveby tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
Idris, The updated groovemount you PM'ed me is a much better fit on the Titan. Thanks Daveby tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
Mine has gap between the top of the groovemount and bottom of titan. It rotates and wobbles slightly.by tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
Yes, also too loose in my Titanby tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
I thought about retracting. I'll have to give it a try.by tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
Maybe the reason I didn't get this with the PP20 is because it has a bit more room for the filament to flex a little. Whereas the Orion has a much tighter (and better, actually) filament path. For now I need to find the best temperature to probe at so I don't get too much ooze but also get a bit of "give" in the filament.by tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
Another interesting thing since upgrading from the PP20 to the Orion: When I first fitted and tested it there was no filament loaded - it triggered perfectly every time once I had tweaked the sensitivity down slightly. With filament loaded but the hotend only at 130C it doesn't trigger consistently. Some times it fails to trigger causing me to hit the Emergency Stop. I never had this effect withby tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
Well, I bought an Orion. Fitted it today and am impressed. It's much improved over the PP20 in terms of construction and accuracy. Good work guys The only config change I needed to make on the Duet is changing I0 to I1 in the M558 command due to the Orion being active-low. My only niggle at the moment is that the groove-mount seems to be a bit loose in the Titan so there's a bit of wobble. I mayby tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
Tried to put a cylindrical section in to separate the filament from the piezo. The dimensions are just too tight with 3mm filament and a 5mm hole in the piezo - too big and it stops the piezo flexing, too small and it causes friction on the filament. Maybe I will get that Orion after allby tekkydave - General
Re: Precision Piezo Z-probe Now available. - 6 years ago
QuoteMoriquendi Somebody had the same problem as you and I think he solved it by putting kapton tape over the piezo before drilling, I wonder whether you could do the same thing but poke a hole in the tape to put the filament through. Idris Thats a good idea. I bought the piezo pre-drilled as I didn't fancy drilling it myself. However, I have an idea for a slight modification to the groovemountby tekkydave - General
