New question. I am planning to use the Pulley V-Slot Build Gantry Plate from the picture but with 3 wheels only. The question is should I use 2 adjustable wheels and 1 fix or 2 fix and 1 adjustable?
I am using them on a " @Phaedrux D-Bot build style " with some minor differences.
Also the PETG printed parts will be ok at temp of up to 60C for motion system ( the same part's like on D-bot build ) At least until I will get all the metal parts made.
@engikeneer what's the thickness of the printed plate ( not sure if this is the proper term for that part) please?
Thanks for the extra picture they will really help me.
@mrehorstdmd this plate is what I am looking to find or something similar.
There is almost nothing to fix the 2020 ( or2040) to the yellow part on the lead screw , except this Nut block
I can move the smooth roads and the ball for bed plate to other location , but couldn't find any option to fix the extrusion to the lead screw.
So I decided to build for my self a new printer , cube style and I am getting stuck at some choice's so hope someone can help me.
First problem is how to connect the threaded rod to v-slot for bed mounting.
Can I find anywhere something similar with the red circled plate or how do I connect the green circled system to 2020 v-slot ?
Picture "stolen" from another member because I may miss the exact name for this
I prefer something metallic because this build will be inside an enclosure and mainly print ABS and other high temp materials.
Can you see any damage or something on the mosfet on the board? Maybe one "leg" is not soldered properly
@fcwilt 1000W 40A PSU too much for the board
@tpyoknig I am inclined to believe that most likely the mosfet on the board is the culprit for your problem
From dozuki manual :
"The ground side of OUT_0 is switched by the mosfet and the positive side is protected by a 15A fuse."
@fcwilt said in Duet 3 6HC Output_0 always on:
@razrudy said in Duet 3 6HC Output_0 always on:
Also the OUT_0 output is controlling a mosfet ( that's the reason for that "thick" wires on output )
I also have separate PSU for the bed controlled by the mosfet.Why is the OUT_0 output controlling a MOSFET?
Frederick
Separate PSU for bed. Is there any other way to control the mosfet?

M308 and M950 are not on the same order. Not sure how important is
Remove the groung from OUT_0 input and leave only the V+ see what's happening.
This is how is mine connected
Still building my enclosure so a little messy at this point.
Also the OUT_0 output is controlling a mosfet ( that's the reason for that "thick" wires on output )
I also have separate PSU for the bed controlled by the mosfet.
Another idea.....connect the temp sensor for bed just to eliminate this from equation too
Ok that make sense somehow. But if you don't power the board how the board will send the command to open/close OUT_0. May sound stupid what I say but why you don't just power up everything the right way?
Connect VIN and after that the bed PSU and test.
No offense just an idea to try out.
Also I am taking in consideration that the "GND" is the one giving the command and ( I may be wrong) but the V+ is "always on" between input and output on OUT_0 as long as the fuse is ok
You're wiring is wrong
The input should be top first 2 pins
Anyone know where we can get the expansion board in Uk please? None of the big reseller have this on stock , not even listed.
Now I can finish the wiring and get the final design for this enclosure
All the holes are from previous boards , displays and card readers......but I will not be changed before everything is in the place
This is what I found and looks like what I need
Plate
And this is the answer I got from them
" They are cast, Machined top and bottom, & coated too "
The coated too may be a small problem but think I can easily trough a glass on top until coating will be gone
After many searches I found that I will need " Aluminium Tooling Plate " is this the right one?
Based on the space I have I decided to go with a 500X500mm ( outer frame 620x640mm ) plate and 400 X 400mm silicone heater. What thickness should I choose? I know...It will be a big challenge going that big...but if I am rebuilding my budget printer at least I am doing something for long run.
Can we use now M205 in mm/s instead of M566 in mm/min for better compatibility with the slicers? Any advantage in one over the other? From @dc42 post , about 1 year ago , the M205 is supported since RRF 2.0.1 for XYZ or other axis. this includes the E jerk too?
I've loaded your files and now I am start testing but so far looks good.
A small problem is that when I am moving to bed centre the speed is very slow.....after X and Y homing the move to the bed centre is very slow.....but after gantry level when is doing the second G30 the speed is normal.
The start.g code is executed first when the board is powered or before any print starts? I need to ad a delay , probe reset and self test for BLT because in 95% of the cases after "emergency stop" or when I power up the board is in error mode.
Can't wait to finish with this and move to piezo probe.....
@T3P3Tony the main rule about exporting from UK is that if a product is "at least 20- 40% made in UK" ( depends of category) then there is no extra taxes. There may be some increase in shipping taxes because of the paperwork the UK sender/ carrier needs to fill in.
On topic...I managed to get myself a Duet3 mini and finally get rid of my last non Duet board on my printers. Now just need to forget everything about Marlin and get fully used with RepRap
Thanks....I will upload the new files and see how it's working. I will do 2 separate sd cards....I will use them in a fresh install and on the old one . Just testing to see if this will fix the map height thing.
@Phaedrux said in Chiron+Duet3+BlTouch:
It's a bit hard to tell from your copy and paste which files are which. It looks like the homing files got pasted into the config.g portion? And that all might be in the middle of bed.g?
M98 P"homeall.g" ; run home all command G30 P0 X42 Y0 Z-99999 ; probe near a leadscrew , the left one G30 P1 X400 Y0 Z-99999 S2 ; probe near oposite leadscrew and calibrate 2 motorsWhere is that from?
This is just a macro I am using to home all and level the gantry. My plan is/was to use this and after that to run G32 or just a single probe and load height map. I level the bed with the stock endstops because I know they are in the same spot always and to make sure the things are as square as possible. After I am doing this I disable the stock end stops and use only the BLT......because the stock endstops are about 7-9mm above bed surface...still trying to figure out how can I use them always and use the BLT only for mesh compensation
In homeall.g don't use M280 P0 S90 to retract the pin. Use M402 instead. That way the firmware is made aware of the pin retraction.
Ok I will change this.....
Also in homeall and homez,
G30 H1 Z-455 F360is not a valid way to use G30. It's just G30 by itself. The speed is set by the M558 command in your config.g. The H1 etc etc will be ignored probably.
Yes everything is ignored after G30....just copied the normal end stops and changed G1 to G30
