That did it!
Thanks Dust & Bob.
Its all working perfectly now, consistent & immaculate first layers on a dished heat-bed.
The probe isn't behaving exactly the same as the one in the video, linked in a previous post.
I still don't see any red LED when the probe deploys and it measures with a small detent, I guess the one in the video may be a v1 microprobe.
Thankfully the microprobe is

I think I may have figured it out, fingers crossed!
I have attached a wiring diagram for the v4.2.7 board.
I found a few other posts of people having similar problems with the v2 microprobe and other boards, all appeared to have the probe connected to a dedicated BLtouch port.
Most appeared to fix their issues by moving the microprobe trigger wires to the z min endstop pins.

I thought I should check the wiring and connections again.
So I removed the board and probe from the printer while leaving all the wiring connected, then I did a continuity test between the pins on the board and the corresponding pins on the probe, all appears to be connected correctly.
I'm really puzzled as to why I don't see a red led when the probe deploys? Every video I have seen of the prob

Thanks Bob,
I have commented out MIN_SOFTWARE_ENDSTOP_Z and re-flashed the firmware.
But unfortunately no change.
Do you think I may have a wiring issue or possibly a faulty probe?

Hi Bob,
Thanks for the feedback.
Z_PROBE_LOW_POINT is set to -2
M114 reports nozzle at zero.
I checked MIN_SOFTWARE_ENDSTOP_Z and it is enabled, should it be commented out?
If the probe is retracted M119 reports:-
x_min: open
y_min: open
z_min: TRIGGERED
z_probe: TRIGGERED
if the probe is deployed M119 reports:-
x_min: open
y_min: open
z_min: TRIGGERED
z_probe: open
Is the "z_min: TRIGGERED"

Ah I see, thank you!
I've compiled and flashed the firmware to the printer.
But I'm having a problem during homing:-
The probe deploys and retracts 3x on start-up.(probe stays blue no sign of a red led during start-up test)
Z goes up by 5mm, X and Y both home correctly, the printhead moves to the centre of the bed, Z goes up by another 5mm, probe deploys, Z goes down 10mm and stops.

Hi Dust,
Thanks so much for clearing that up.
When setting:-
#define Z_MIN_PROBE_ENDSTOP_HIT_STATE LOW
Should I also set:-
#define Z_MIN_ENDSTOP_HIT_STATE LOW
I seem to remember they both needed to be set to the same state in older versions of Marlin?
Also, should I change:-
#define SERVO_DELAY { 300 }
from 300 to 500?
As far as start gcode goes, do I just add a G29 after the G28, like the BL

HI all,
I'm trying to configure marlin for a BIQU v2 microprobe on an ender 3 with a v4.2.7 board.
I have made my way through the "MicroProbe V2 user manual" and I think I have marlin all configured correctly.
But to be honest I don't really have a clue what I'm doing.
The manual shows how to connect the probe on various BIQU boards, under each board is some custom info/code, can anyone explain

Apologies for the slow response,
Ah, not too outrageous then. I thought it may have been something like 15mm retraction.
Ohhh, very nice design!
Quite a bit cleaner than the Sherpa mini, how do you find the little nema 14 performs. Does it tend to run quite hot?

Thanks for the replies,
Oh great, that's good to hear.
Wow almost one meter bowden! out of curiosity, can you remember how much retraction you needed for that setup?
What sort of extruder did you use?
Ah, I have seen this video! such a shame an official bondtech product does this.
As the youtuber mentions, I wonder if changing the design to Helical gears could possibly fix the issue.

Hi all,
I would like to modify one of my printers for high temp printing, I dabbled with a v6 clone years ago and found all metal heatbreaks quite troublesome and prone to clogging.
Most likely low quality kit and heat creep, all the fancy modern hotends look as if they have a very short transition between the hot and cold side.
Does this mean that they only work well with short retractions? (1m

Hi all,
I have been trying to get a reprap discount full graphic smart controller running correctly on a BTT SKR v1.3 board, running Marlin 2.0.
But I just cant figure out what I'm missing. I have a line of dead pixels running across the screen just above half way up, Its at just the right height to cut off the top of the numbers any time you try to edit a value.
Also the first screen that displ

Thanks for the suggestion Obewan,
The Retraction At Layer Change option was disabled as default, I have set this active now and very slightly increased the flow rate to 104%.
I have just finished re-printing the parts, but unfortunately the tweaks have had little to no effect.

Hi all,
I'm printing with BQ PLA at 200 degrees using Cura 3.0.2 on an Ender 3.
Cura is set to 3 top and bottom layers and 2 perimeters, (Inner Perimeter first, Outer Perimeter and then Infill) Flow rate is 103%.
Small parts and retraction tests print great, but larger parts have 10-20mm of weak under-extrusion at the start of each perimeter.
This was the retraction test I used -

Srek - Do you mean, tie both the negatives together on the D/C side? (sorry just have to be sure)
dc42 - That's good to know, thanks. So is this only a problem when running the drivers on 1/32 ? can it be avoided if i set the drivers to 1/16?

Hi all,
I would like to swap out the mighty board in my CTC Dual for a ramps board with DRV8825 drivers.
The CTC is a 24v printer, so all the heaters and the stepper drivers will be connected to the 24v supply.
But the arduino, LCD and a few ancillary bits need 12v.
I have a spare 12v PSU, is there any reason I shouldn't run both 12v and 24v power supplies in the same printer from the same main

Hi Francois,
Thank you for you response, sorry this reply was so slow.
That's a very interesting post!
Its a real shame skeinforge requires custom code just to produce viable support material, unfortunately editing code to that level is well beyond me!
I think that post ultimately says that I should be using slic3r instead, lol.
Do you know of any other slicing software I could try out that is c

Hi all,
For the last year I have managed to get away without needing any support materials for my models up until now!
I have been working on a new design that will require some internal support so I decided to pump out some basic bridging models and try to get my support material dialled in.
I managed to get 90% of the settings just as I wanted, but no matter what I tweak I cant reduce the bond
