LCD Blanks when doing sensorless homing on y axis in Marlin 2.0 - 4 years ago
I have been trying to setup Marlin 2 on my modified Ender-3 (Einsy Rambo) and am having some issues with the LCD screen blanking during sensorless homing of the Y axis. The homing competes and the printer responds, but the screen is blank. I didn't have this problem with 1.1.9. Any ideas on why this might be happening? UPDATE: Went back to 1.1.9 and it is doing it now. This is about par forby ElmoC - Firmware - Marlin
Re: PLA safe for use in an aquarium? - 5 years ago
The PLA it self maybe "food safe", but is your printing methods food safe? Are all parts of the filament path food safe? If you have expensive fish, I wouldn't risk it. Maybe make a mold of an object and use aquarium safe materials to cast it.by ElmoC - General

I did write to Zesty about replacement blocks and got a reply back that they are sending out replacements ones. Not sure why, but wilby ElmoC - General

If so, it feels durable enough. My only concern is how small it is and with no tether, it could be dropped and lost. I haven't check about replacement unby ElmoC - General

QuoteHergonowayGeneral question : does anyone used the piezo mount with a flex3drive or a nimble? I'm currently thinking about leaving the world of long bowden to more direct drive approach. I am running a nimble with the piezo on my delta. Loving it.by ElmoC - General

QuoteHergonoway Hey @DjDemonD, what's your DUET configuration on your delta with the piezo installed ? especially M566, M203, M201 and M906 We've got similar build, maybe I'll find a better tuning to perform fine print. I am using the identical settings for mine that DJDemonD uses with great success. I do have a couple minor differences in my M558 command... M558 P1 X0 Y0 Z0 F300 T3000 H2 Rby ElmoC - General

QuoteDjDemonD As for drilling a hole, get a spur point wood drill bit. Mark the centre of the piezo disc.place the piezo disc with ceramic side upwards, on a disc of blutack which dissipates the heat and stops it spinning around. Press down with the point of the drill bit on the centre mark, it will puncture the upper metal layer, thereby remaining centred. If you place the piezo disc with the cby ElmoC - General

Okay. So it sounds like while the electrical connection gives the best accuracy and repeatable results, but at the cost of being able to print. Doesn't sound like too good of an option. Think I will stick to the piezo and my BuildTac and Zebra Plate for now.by ElmoC - General

Ideal applicator would be a smoothed shank machine screw with just 3mm of thread on the end. I use a long m3 machine screw, the heat slightly taps a thread into the plastic but this doesn't affect how the product works.

Re: Precision Piezo Z-probe Now available. - 7 years ago
Quotedc42 QuoteDjDemonD The other thing that's very useful is lowering acceleration, motor current and jerk before probing, then restoring it afterwards. Once you have configured recovery time, reducing jerk should have no effect, because jerk is not used in Z probing moves. I wouldn't expect reducing motor current to be necessary either, unless you use low microstepping and the resulting vibratby ElmoC - General

Re: Precision Piezo Z-probe Now available. - 7 years ago
I did talk to him about it, but he didn't seem too enthused about it. His last comment didn't make a lot of sense to me. Sounded almost like he was saying slower acceleration would be good, but then at then end says it wouldn't help.by ElmoC - General
Re: Precision Piezo Z-probe Now available. - 7 years ago
QuoteDjDemonD I was trying to decipher the duet wiki about this. How are you using it? You just use M906 twice. Once as normal with the regular currents. Second with the H1 parameter for the probing currents. M906 X1000 Y1000 Z1200 E600 ; Set motor currents (ma) M906 X500 Y500 Z500 H1 ; Set motor currents for probing These are just made up numbers right now. I don't have the probe on myby ElmoC - General

Quote The other thing that's very useful is lowering acceleration, motor current and jerk before probing, then restoring it afterwards. If you are using RepRap firmware, like Duet, the jerk is not used during probing. Also, the M906 command to set the motor current allows the use of the H parameter to set current during probing so you will only need to adjust the acceleration.by ElmoC - General
Re: Precision Piezo Z-probe Now available. - 7 years ago
QuoteDjDemonD R is recovery time, I believe it waits for the specified time after a move to a probe point before beginning the probe. This cuts down on the effect of mechanical noise which seems more problematic on cartesian machines than deltas. That 0.2s definitely made a difference on my Delta.by ElmoC - General

Re: Precision Piezo Z-probe Now available. - 7 years ago
You might need to readjust that left pot again. Turn it clockwise until the blue led comes on and then keep turning until it goes back off, then turn just a little bit more. Not much. You should be able to get it to flash with just a lite tap from a tool handle against the nozzle.

Re: Precision Piezo Z-probe Now available. - 7 years ago
When you say it isn't probing, do you mean it is not seeing the nozzle touch the bed or you start the Auto Delta Calibration (G32) and nothing happens?by ElmoC - General

You sure that Z-150 is correct in the final G1 command? The bed is normally Z=0 with positive values going up. Using a negative value would drive the head into the bed.

Re: Piezo support. - 7 years ago
You might want to drop the P value in the G31. The lower the value, the quicker the firmware responds to the touch. Just don't make it too small or you will get a lot of false triggers. I run mine at 10 with very little issue. May bump it up a bit if I start seeing false triggers again.by ElmoC - General
