I am curious about the two, not so latest, items ( on closed loop steppers) that I have come across recently and would like to know, in order to use them, if a) Both of them are good; where the difference boils down to price, skill etc. b) One is better than other; say based on ease of use, accuracy etc. c) Both of them are useless; say with respect to the return of investment etc. Here are theby sudarshan - General

Same. Milled brackets/plates do a similar job, but if you have a flat surface as described above, it would be easier. (Note: first connect the extrusions with the bracket, preferably on a flat surface. Then bolt the extrusions together.)by sudarshan - Extruded Aluminum Frames
Rotation is prevented by the force of the bolt. Friction in other words. You can use milled brackets to ensure no movement, along with the digital dentist’s method.by sudarshan - Extruded Aluminum Frames
It seems like I will have to wait for the duet board. Meanwhile, any opinions on re-ARM and stm32 nucleo?by sudarshan - Controllers
I wish to make a tool changer type printer. Is there any cheap board (below 100$) which I can use? Would klipper be helpful to substitute the lake of 32bit board thereof. Kindly suggest.by sudarshan - Firmware - experimental, borrowed, and future
I was going to purchase the re-Arm until I stumbled across the comments here. So what options do we have now? Is stm nucleo the sole alternative? Or duet board is the sole versatile board and we will have to wait till prices come down or a new board comes to market? Bluntly speaking, are there any 32bit boards below100$ which can give reliability and versatility comparable to duet? (plus is marlby sudarshan - Controllers
I am going to see a creality CR 10 within a week ...but....can anyone explain me how different it is from the Son of mega max....I have a little confusion.....with all that sturdy frame , industry actuators etc... It still has to print slowly for good output....but so is the case with CR 10....then where is the difference?? If my prints are great with the slot bearing guides....why should I goby sudarshan - General

Would you like to share info about your diy bearings? Or can you suggest the proper arrangement for the same ,which is based mostly on off the shelf parts. I was about to order linear guides and metal plate for milling to make a G&C all metal type printer. But if you can provide some sample prints and comparision (not random prints but sustained printing comparision of um gantry and corexy orby sudarshan - General
No Printed parts are a precondition in our machine....for two reasons....first...there are not printers who can do the job adequately, thus we need standard parts to accomplish the same and expand the community....second printing is inherently limited in accuracy in FDM so for proper performance it's essential that we rely on standard equipmentby sudarshan - General
I have a welded iron cuboid that I got off as scrap from a local hardware store....they used it like a table(unable to post photos)...it's not very big but quite decent in size.but i guess I can get at least 35x35x35 volume out of it.....it does not wobble... However I am concerned that how will I be able to align my mechanism accordingly. My ideas.....shall I mill a metal plate for fixing a corby sudarshan - Extruded Aluminum Frames
This is the stacked belt corexy arrangement that I intend to put in the machine....can anyone help me out in the construction??by sudarshan - General
CWAA.....I met with the local 3d printer owner she in my town....no so many but all of them had corexy....I guess I will have to go with the corexy model for the time being as I will be dependent on their expertise and supply of raw material for day to day help I need my construction....or I have not realized the full potential of the reprap community....but if you can provide a counter solutionby sudarshan - General
I was wondering if it's of any help...my neighbor has a small table for cutting lumber...it's a small all metal table...I had the opportunity to check it last Saturday...it was a cuboid ,welded and was made out of steel beams with shelf bracing at the bottom and two support beams at the top....thus it had zero wobble and was sturdy..can you tell me why or why not it will be ideal for making a prby sudarshan - General

Budget is not that big a problem.....I want to incorporate the ideas of costlier printers into ours.... not in parts cost but by reduction in labor cost, marketing cost, profits etc. Plus, I am ready to sacrifice speed to get accurate and precise prints...however that's where the delta seems to loose steam...one of the delta owner I know complained frequently about the bearing on the printhead...by sudarshan - General
Newbob....you are right....the Veblen effect is not worth giving into.....I want to find out the techniques which yield better prints. like..sturdy frame...good print bed....playless guides...zero backlash screws and nuts or belts..etc...I want to know which companies takled these problems....and how did they do it...and how can we do it...which are the better sources of getting good quality parby sudarshan - General
I do not intend to go for the high price tag...but I wish to find out what are the features,which improve the performance...for incorporating them in our design and making the available to all. Did anyone notice that they don't use linear guides for that high price tag?by sudarshan - General
Trexation...newbob thanks for ur inputs....I am looking into the gigabot by re3d....any ideas on that? P.s : correction of the exact name of the printer and company.by sudarshan - General
Thanks for the input jinx... I have already gone through the hypercube documentation....it can be a great option if we can improve the frame by adding gussets.....refer to the article on aluminum extrusions on hackaday....however it would be even better if we can use least amount of 3d printed parts in it....Plus I plan to use profile linear guides...any suggestions on that?

Hi one and all, It's my first thread on the forum. Pardon me for any mistakes, I would be glad if someone would point them out. The purpose of the thread is to find out the best 3d printer to be made at home , with the following specifications: 1) highest quality of prints. 2)lessfailures. 3) which implies, sturdy construction......specifically according to the digital dentist's parameters.(incluby sudarshan - General
Try to make a prototype....you will be a star overnight.... Jokes apart...have you tried the xaar 1001 printhead...they are versatile and can even print ceramics...they are meant for flatbed printing. i guess there is a ytec3d forum in it.by sudarshan - Developers
