Hi all

Just wanting to pick your collective brains.

I'm building my own custom 3D printer it is a CoreXY design the CoreXY part I have all sorted and tested and I'm happy with that.
I'm...

An arduino or other microcontroller is a good idea.. if you don't have programming experience or want a simpler solution you could use a temperature control module which would integrate with the...

Sounds To me like the z axis feed rate or acceleration its set far too high in marlin.. can cause the nut on threaded rod to lock up!

In the firmware there will be a setting for the probe offset.. which its the distance from the probe to the bed check that it had not been set.

Typically you need a geared extruder for 3mm filament,I use a bulldog xlnt, however the Greg's wade extruder(reloaded) is also an excellent choice.

Sounds like you need to alter the offset between the hotend and the bed.. if you look in the marlin config file for "#define Z_PROBE_OFFSET_FROM_EXTRUDER"

You can also use gcode to set it "M206...

I've only just read this post thought I'd share a distance sensor I was planing on using its an omron ee-spy302 it is a phototransistor senses up to 4mm and has a very wide input voltage range (5v to...

Fuses are settings on the controller board they do various things such as set clock speeds, bootloader options, brownout detection etc.
You would need a chip programmer to change these settings...

I also use octoprint to monitor my prints ... My controller board is a Smothieboard there are plenty of spare output ports on them and its as simple as adding in a new gcode command in the config to...

Smoothieboard x5 will support that. you can run the 2x X-axis and the 2x Y-axis from a single stepper driver eg 2x nema17 motors with a maximum current draw of 1 amp each and set the stepper current...

Are your steps per mm set up correctly?

Looks like you have adhesion issues .. if its abs you are using try abs juice (abs dissolved in acetone) if its pla try pva glue

looks like you had the software endstops set (you can disable them for testing)

the Z motor sounds like software problem if you swapped the driver over and it's still doing it, you should have...

there's a couple of things it could be


could be that your steps per mm are not set correctly in marlin
your endstop configuration might be stopping them / or the endstop wiring

its quite common to use a computer power supply my first I3 used one. 400W should be the minimum .. you should also use load resistors to increase and stabilize the maximum output of the power supply...

I buy a lot of stuff from we do 3d printing uk based 3d printer parts and kit supplier.. they have pet-g in stock says its not on the reel but they do up to 1kg of it .. should be easy enough to put...

thanks for the info.

I'm probably over thinking this I'll build the printer see if I have any problems first with the metal print bed, just checked it would actually be cheaper just to scratch...

thanks for the reply I went for a 8mm Lead screw with a 2mm pitch.

I'm still building the printer I have the frame and motors fitted I haven't tried them out yet, but they do move much smoother...

I'm planning on using a inductive proximity sensor so I really need to have a metal top layer on the bed

Hello everyone

I'm in the process of Building a new printer, I should be getting my heat bed sorted out tonight hopefully (soldering the thermistor and power leads and some braided cabling etc) I...

I've got 2 hexagon hotends, 3mm with 0.4 nozzle .. I chose the Hexagon over the e3d because it was cheaper and there was no ptfe lining tube. my previous hotend had the lining and it caused all sorts...

this is a simple thing to do in your slicing program (i use slic3r) there should be a section for custom G code at the beginning and end of the print .. simply seting a G code X,Y coordinate at the...

just checked my configuration file for my Smoothieboard (i set current in my firmware) and all my steppers are set to 1a I think i turned them down a little. when it's higher they would constantly...

there isnt a lot of clerance above the 8mm smooth rod for the Y Carriage (unless your going to raise it up a little) here are some pics of the plastic parts you can see the smooth rod sticks out the...

I bought a bulldog xl to use as a Bowden for 3mm filament I got nothing but problems with it .. I ended up ditching the Bowden and going back to direct drive it works great now.

As for stepper...
