I have a MKS SGen V1.0 hooked to a TFT 35 V1.0 using Trinamic TMC2209 Drivers, running on Smoothieware. I am having issues with the printer being consistent and more so it will be printing fine the just stops dead no control on screen works the hotend fan stops sometimes and sometimes just keeps going. i do have power recovery so i just turn the printer off then resume print but leaves a blob paiby bbcbggr54 - Controllers
I am building a Railcore 450 X450 X550 using t10 leadscrews and was wondering why i couldn't mount the z steppers up top with everything else and not have to worry about weight twist and whatnotby bbcbggr54 - CoreXY Machines
just wondering why most printerspush the bed up from the bootom as to the inverse hang the bed off the motor on top? all stats say it is better to hang the bed motor on top. So why is it strucural stability on top not able to hold the loads or make it too top heavy? These were my only conclusion. What do you guys thinkby bbcbggr54 - Mechanics
Im building a corexy same design style as the RAILCORE but with a Smoothieboard. My problem is finding the best external stepper drivers for the z motors as mySmoothie5X doesnt have enough drivers. I like,understand TMC drivers but they will not work with Smoothie as far as i know? I dont really know how or where to look for other drivers. I will have a fairly heavy bed at 400X400 aluminum,silacoby bbcbggr54 - Smoothie
I love this setup with 3 motors 3 guides. I have designing a printer almost identical to this but was having issues with z config. Its going to be big 400x400, and heavy though aluminum, heated, magnetic bed, so i need allot of power on the z axis in order to b smooth. now my issue is trying to find the right drivers for a smoothieboard 5x. i dont think i can use the tmc drivers can i? or shouldby bbcbggr54 - CoreXY Machines
i am building core xy 400x400 and need a spring steel sheet for my bed to act as a flexible removable build surface but i am having trouble finding a piece that large. i was hoping someone might be able to give me some advice on where to get a piece. i live in nova scotia canada.by bbcbggr54 - Mechanics
sounds like noone seems it to be an issue. i understand how to clean prep material, i will definetly use something like an epoxy over superglue as i need some body to the glue. i will be using it to glue together XY carriages and bracing for tubes etc. so it does need to hold and be rigid.by bbcbggr54 - Mechanics
i am bulding large core xy and want to make some pieces out of aluminum but would need to weld pieces to make a part {plates to tubes etc.}. i dont want to weld them as i dont use gas with my welder, dont have a spool gun, and dont want warpidge. therefore i must braze but that is allowing for warp. so glue together with permabond, or an epoxy. maybe what bodyshops use. any advice on if any typeby bbcbggr54 - Mechanics
i dont understand whats wrong with it could you explain how im overconstrainedby bbcbggr54 - CoreXY Machines
no excuses is right they are the best i can think of or seen. which designs are better i havnt seen them? this build is up for discussion not just negatuve remarks i am a rookie.by bbcbggr54 - CoreXY Machines
do you have yours mounted on top and what are your leadscrew mountsby bbcbggr54 - CoreXY Machines
So i have these 3 Z designs to choose from unless someone else has something better. No cantilever designs as this is going to be 400X400 heavy bed assembly. I have had reviews that the 3 leads and 3 rods is over constrained but not on the 2 leads and 4 rods which i dont understand as i have 6 points of contact with each. The rods will be have solid steel mounts. We can talk about lead mounts. Iby bbcbggr54 - CoreXY Machines
so you 3 16mm rods wouldnt be thick enoughby bbcbggr54 - CoreXY Machines
when you end supported rails do you mean rods cause im using rods and can make them rock solid on the ends trust me thends should not flexby bbcbggr54 - CoreXY Machines
most of my parts will be made of aluminum once i have it running goodby bbcbggr54 - CoreXY Machines
as for the happy dog if my leadscrews are straight and hanging where do i get the twist? or is it that to get perfect straight Lscrews and alignment is damn near impossible therfore you will always have at least a little wobble. i want to hang the leadscrews but i cant see how to drive them from the bottom and not have both sides fixed. as well as it is the most efficient way to run a Lscrew.by bbcbggr54 - CoreXY Machines
i meant rod not rail in last statement and iwent for rails just to give me more stability. carbon fibre rods for light weight, steel rods for cost, strength and it is the z axis.by bbcbggr54 - CoreXY Machines
i was thinking three leadscrews for a more stable lift no twisting and 2 motors because i dont think one will have the power. and with seperate tensioning on the belt i might be able to eliminate the push pull effect. do you think one would do or just go to nema23 as i am running polymer bearings. would my rails keep it stable enough to just use 2 leadscrews.by bbcbggr54 - CoreXY Machines
i would like te motors on top but my belts would get in th way of filament and air being fed to the extruderby bbcbggr54 - CoreXY Machines
Z doesnt have to be a rocket but i do want it to be smooth and have no resrictions on speedby bbcbggr54 - CoreXY Machines
i understand the point of linear rods but if i can get a near perfect double fixed leadscrew assembly i can be faster and little to no z wobble. and is it not better to have the leadscrew holding the bed up instead of pushing so you get even less bending therefore less z wobbleby bbcbggr54 - CoreXY Machines
Belt stretch is more of a maitenance design i will always be checking if the belt is getting worn just from constant strain i like the idea of three lifting points just much more stable in my eye. i do like your bed mount design as well as cam endstop profiles.by bbcbggr54 - CoreXY Machines
Hello everyone! This is my first build i have a mpselect mini but too small and lightweight still a wicked little entry. So i go big and rock solid and light as i can .Everything will be made of steel except moving parts will be aluminum or printed. I will be using 16mm chrome rods for z axis, carbon fibre x axis and im thinking on hiwinn hgr15 for y axis anyone have reviews on the hgr? using smoby bbcbggr54 - CoreXY Machines
