Hello all,

Been working on my Senior Project of Water-cooling a Tool-changing 3D printer with the goal of printing HT Plastics (PEEK, PEKK, Etc.). I am using the HevORT as the "printer" and using E3D's hardware for the tool-changing operations.

I am looking for redundancy here, I want a "failsafe" for my water loop should my pump stop working. I found this "flow indicator" and from what I see, it uses a 3 pin connection, and typically plugs into a fan header on a motherboard, this makes sense to me.

Check it out HERE

My question is, how would I trigger an "E-Stop", or "Kill heat" command with this Flow meter's Tach reading "zero", which would indicate a stoppage of flow.

Let me know if you have any ideas.

Thanks in advance.

@fcwilt @engikeneer @Nuramori works great now and levels great, thank you, stuff was massively screwed up. Thank you for your help I appreciate it.

@dc42 said in Configuring 10K Water Temp. Sensor:

If it's a 10K thermistor than you need T10000 in the M308 command (assuming RRF3). The B value you need depends on the thermistor. As the temperature range of interest is low, you can use C0.

Gotcha, I just chose the 10K option in the RRF Config Tool, (which I couldn't figure out before how to get to pop up), and you can see the temperature results below.

Thanks for the help.

@phaedrux well to be honest I believe it was the M997 B1. Because I had previously been on 3.2.2 on the mainboard and did the ssh Sudo upgrade stuff in the pi and it did not change to a newer version on the mainboard. But I did do both, so I don't know with 100% certainty, apologies.

@phaedrux Ok, should I take the SD out and move this file into the /firmware folder I created?

Looks to be working now, thank you so much!

@phaedrux Download and load 3.2.2 onto the SD card? Then send the M997 S1 command? Or do 3.3 and send command?

So on my Rostock Max V4 I upgraded the firmware to RRF 3.2.2 with no problems, things were working fine. In my mind, I thought it would be completely fine to upgrade to 3.3. So I sent the M997 S3.3 command and it upgraded. The duet would no longer connect to my WiFi Network.

I've tried messing with starting, stopping, resetting, trying to reload 3.2.2, etc.

I am now stumped and out of ideas, I feel it can't be too complicated, when I send M115 I get a RRF3.3 and Duet Wifi 1.02.

I feel like it is an incompatible version of the wifi file with the new /firmware folder within 3.3 (different than /sys in 3.2.2), but I do not know.

Is there a way I can just go back to 3.0 clean slate? Then I'll upgrade to 3.2.2.

Let me know what would be the best course of action.

M122 Command:

M115 Command:

@fcwilt Ok, that's kind of what I was thinking. Here is my layout. Btw I have Duet 3 6ch MB and Duet 3Ch daughterboard with SBC Raspi 4.

I also am using E3D's toolchanger, therefore the C-Axis.

Mainboard:
Drive 0: X
Drive 1: Y
Drive 2,3,4: Triple Z
Drive 5: C axis (toolchanger)

Expansion Board:
1.Drive 0: E0
1.Drive1: E1

Does this clear things up? I think we were getting some wires crossed haha.

So would this be correct to correctly map what I have above?

@fcwilt said in Triple Z Ballscrew G32 Leveling Wrong Direction:

@jordan_miller41

Your M584 has this: M584 X0 Y1 Z3:4:5 E4.

Let's assume that is correct - for now.

Then in the M671 the first X/Y values must refer to Z3.

Likewise the second X/Y values must refer to Z4 and the third X/Y values must refer to Z5.

And, of course, each stepper in Z3:4:5 must actually be connected to the stepper that is near those X/Y values.

And the G30 X/Y values in bed.g don't really seem to match up well with the values in M671.

If things are not in sync the process can make the bed less level.

Now back to your M584:

You have Z4 and E4 - one of them must be wrong.

Frederick

Can you explain to me what the E4 vs Z4 thing you are talking about is? Is E4 even needed, I am kinda confused.

@fcwilt @engikeneer @Nuramori works great now and levels great, thank you, stuff was massively screwed up. Thank you for your help I appreciate it.

@engikeneer that would make sense now wouldn't it. Thank you for pointing out my blindspot.

@fcwilt Ok.... I followed @Phaedrux 's article he tagged and have my motors flipped, when I move with the G92 command I get my proper +Y to the back of the printer and +X to the right of the printer. Origin being at the front left corner of the build plate.

The next issue I had to deal with was flipping my pins for X&Y endstops, I have X working as it should, but no matter what I change, the Y-axis goes to the back of the printer (Ymax) and not to the front. I changed the M574 Y1 S1 and it still wants to move to the Ymax. So I am kind of at a loss here. Not sure what is happening, I am sure it is something simple I am missing.

@nuramori said in Triple Z Ballscrew G32 Leveling Wrong Direction:

@jordan_miller41 can you share your entire config.g file?

Where are your endstops located?

End stops are located left side for X and Front Left for Y. I do remember having the Y setup to where the homing is at the maximum and I think it was because it went the wrong way initially, I could be remembering wrong as this was 6+ months ago when I first started.
