Hoping to get some feedback on this design of a XY Gantry
A Special gantry for openbuilds vslot using Mini V wheels
it also include the ABL (Auto Bed Levelling) Micro switch so when pressure is applied to the nozzle it hinged upward slightly to trigger the microswitch

never heard of a pei coating on aluminum, I have a piece of PEI plastic 1/32" thick mounted onto Boro Glass

I have used the same sheet of pei for one year, with hundreds of prints on it so far
I have had many nozzle touches without issue
ive had a hot hozzle sitting on the surface for minutes without any damage
I dont usually clean the surface, dont need too.
I also tend to print with PETG

if this is something that only needs to happen once and never again. and could affect users. might be something that you should apply to each product before it ships
just incase users do not have a strong enough heat bed.

IF after the above you still have issues with your ABS you can seed the bed with a very very weak ABS/Acetone solution, paint it on when cold, then clean the bed again with just acetone and clean cloth/kitchen towel. OR wet a kitchen towel with acetone, drop a short piece of skirt onto the bed and wipe around, and then clean again with just acetone kitchen towel. This should sort y

I loaded up repetier and can control it no issue. when i try Marlin 1.1 RC3, RC4 or RC5 Bugfix
i cant connect unless I turn off start up code in simplify3d but then it wont respond to gcode
also when I try to connect with S3D i notice that the rumba resets.

more robust then Pei?
pei has a higher melting temp then the typical nozzle temp even for ABS/PETG
hitting PEI with a hot nozzle does Zero damage in my experience.. not sure how much more robust then Zero damage you can get lol

this stuff sounds basically like PEI. is it?
if not what makes it better then PEI?

I installed Marlin 1.1 RC5 (bugfix) on my Rumba board, via Arduino IDE. with no issues
Im running Windows 10 64
I installed simlify3d but i cannot connect to the rumba
Ive tried different ports, USB Ports, USB Cables, Drivers
sleep disables on USB Hubs/controllers
two different computers..also tried with Pronterface.. cant connect to control
Baud is set to 115200

Your problem is that your printing with ABS.. its not a safe plastic. Try Petg it doesnt shrink/ warp nearly as much as ABS and its safer

I see people always mounting a Linear Rail to some extrusion. if the load is light (1kg) and the span is 20 or 30 inches
is full support required? or can it just be supported on ends.. assuming a 20mm rail

You could use more than one belt.
Does that just introduce more slack / tension issues

1 Motor driving 4 screws, seems ok. but finding a long Gt2 Loop that is over 2000mm is a challenge
RobotDigg deliver belts up to 50m length
Yes but they have a min qty of like 100 belts I believe.

Do you still need endstops when using a servo?
or does it just know its limits.
If power is off does remember its position when powered back on?

Check out these servos from Teknic called Clearpath
they are "reasonablly" priced lol at around $350 each
not sure how easily you would be able to use this on a Mega board/ Rambo
smalled size is Nema 23
I wish they made a Nema 17 size for $200

Im working on a CoreXY 12"x24" printer
with a fixed Build plate and moving Gantry using the Quad Lead Screw setup. and using Vslot to help keep it aligned.
still designing.
this thread is helpful. kinda worried about binding.

need to put this into some perspective.
I think this is a device that can be patented. it has some development required to produce it.
its fairly unique
compare it to this

Can anyone tell me how many microsteps the drivers on the Duet support.
is there any point in using a 400 Step Nema 17 vs a 200 step one with the Duet?

Based on my guesstimates using that calculator I need 26 oz/in of torque
and the stepper i want to use makes 66 oz/in torque, at full power
Thanks for the link. makes me feel more comfortable.

So how do you know if the 3d printer your building will work fine with a nema 17 or if you need to opt for a high torque 17 or a Nema 23
without testing
I am in the process of building a 12"x24" CoreXY machine using openbuilds vslot rail an wheels. but im concerned that going with a 400 step Nema 17 wont have enough torque.
but i want the positioning ability

Cant say i have any so far. as im still waiting for my Duet to be delivered. but while im waiting i have been reading up more about how to apply firmware and changes and it seems like there are not many users of the reprapfirmware for duet. and even finding videos or tutorials seem scarce.

Wish a version of Marlin or Repetier was available for Duet

Found these Silicone heaters on ebay. they come prewired for 110v AC
also come with digital temp control
the idea of having a seperate control and not needing to control it in Gcode is appealing
Thoughts?
