Noob building a HEVO in need of help.

[oliof]

Bonus answer to question 7: the probe offset is plus X when it's to the right of the nozzle. The value is the distance to the nozzle, or how you would need to move the nozzle to get to where the probe is.

New parts installed, and new problems.

I have changed to a e3d Hemera with vulcano hot-end and 40w heater, duet magnetic filament sensor, Piezo Orion, PT100 with duet daughterboard. The magnetic filament sensor is not setup yet.

1: I need help with the piezo. I have changed the config.g and got it working, but only when i tap the hotend. When I try to home Z the bed is pushing the nozzle and extruder up. It does only trigger with a tap, not bending slow upwards. If I change the sensitivity on the board it triggers of the machine it self. I did try to increase the speed on the z-motors, but it seems like I can't get them to move any faster. What should i try?

3.3V / V+ Red wire
GND black wire
Sig Green wire

2: The PT100 is working, but if I touch or bend the cables on the sensor it shows 2000 C on the display and the fan starts to run. Can this problem only be intermittent connection? Sometimes it shows the wrong temp aswell, like 46C when it should be 23C/ room temp.

M558 P8 C"zprobe.in" I1 R1 F3000 X0 Y0 Z1

You should remove the X0 Y0 Z1 as that's not been used for quite some time.

You've got a probe speed of 3000, and your config has M203 Z3000 as the limit, but is it actually moving that fast?

You're also missing a travel speed so try adding T6000 to your M558.

You should also consider lowering the Z axis motor current during the homing routine to reduce the risk of damage if it doesn't trigger.

It sounds like you have a bad connection with the PT100. Could be damage at the cartridge or the connector plug, or even the wire.

I have removed "X0 Y0 Z1" now. I can't see a difference on the bed speed when i changed the F-value. I added the T-value now and the bed moves fast, but it still crashes with the nozzle. The Piezo is very sensetive to vibrations and taps, but does not trigger when pushed. I installed one rubber damper on each z-motor, and the vibrations became worse.

The cable on the PT100 broke off inside the connector today. I have installed a thermistor for now, but i can't find all the values I need. Should I use 4300 as the B value? What about C and H?

I think it is this one: Thermistor 61-0452.pdf

The Z speed is limited in M203 as well as set by M558, so if you want to raise it you'll need to raise it in both places.

If your thermistor is from e3d, see here for the settings: https://e3d-online.dozuki.com/Guide/V6+RepRap+Firmware+Configuration/26?lang=en

This is the kind of document I was looking for. Yes, I got the bed moving fast, but the piezo won't trigger when the nozzle hits the bed now either. I am going to send an email to them and see if they got any suggestions for me.

Time for an update! Good and bad news as always.

I have had a lot of strange software bugs in the past.
1: The wifi won't always connect, I have to restart the printer
2: The axis won't home every time I try, sometimes there is no reaction, I have to restart the printer
3: I got some strange error in my macro files. It's not actually errors. The macro files were overwritten with these two lines.
Load and unload filament: Error: Bad command: {"main":{"language":"en":, "lastHostname":"192.168.1.38","darkTheme":false, "useBinaryPrefix":true
G29 macro ; Unload 20mm filament G1 E-20 F2000me":"192
I changed the load and unload manually and the commands are working again. The G29 macro was deleted.
4: The printer does not load the configs on the SD card always, I have to restart the printer and take the SD card out and in.
This is the error message that was generated in the load and unload filament macro.

The printer is up and running with a Hemera, IR probe, PT100, magnetic filament sensor and a chamber heater. I never got the Piezo to work with my setup. The enclosure is painted white to reflect a light source inside. Plexi glass and 4mm plywood. Magnetic door "lock".

The chamber heater connected with a SSR relay controlled by the Duet.

During the building process.

I made a cable support and the filament holder with bowden holder.

This is where i noticed the wobbling.

Next on the list:

• Further adjustments to get better print quality. I have already reduced wobbling.
• Prototype a new version of the extruder mount. I am losing to much space in the axis because of the size of the Hemera.
• Buy linear rails. The x and y rods are flexing.
• Buy and install LED light inside the enclosure. Any tips?

I am trying to edit my last post, but I got this error in the forum: Post content was flagged as spam by Akismet.com

I had a bug in the web interface with the icons, but they was fixed when I updated the firmware and the web interface.

@Quattro, looking at the picture, your piezo seems to be attached below the extruder, not between the hotend and the mount as shown in this picture:

Are you sure it is supposed to work that way, just getting triggered by it's own mass?

That would seem to indicate that you've got some junk data in the macros maybe?

I see that you're running firmware 3.0 but can't tell exactly which DWC version you're using. It may be time to update to 3.01-RC10 and DWC 2.1.5 that just came out. Much has been improved since the first 3.0 release.

I could not find anything fuzzy in the macro files. As I wrote in the last post, I have updated to the latest version now. The icons is fixed and i hope everything else is good aswell.

The Piezo triggers when it senses a force, like a g-sensor. I could not adjust the sensetivity to where it did not trigger when moving the bed and when it triggers when the bed hits the nozzle. I've seen many different mounting solutions with this probe. I am not a expert, this is just my observations. As I wrote, I have switched to a IR-sensor and it is working fine.

To anyone wondering, this thread is a mix between a build thread and "I am a noob and need help"
