what is the dimensions of this version of the board? I want to see if it will fit....by patrickrio - For Sale
Hi (probably specifically to dc42), I am now ready to fire up my CoreXY build for the first time. Here is my previous thread: Hiwin based CoreXY Quotedc42 There is a list of resources here . Here is a summary of what you need to do: 1. Download a binary of my firmware fork (the only one that currently supports CoreXY) from . Follow the link to the latest version, then click on the Raw buttonby patrickrio - CoreXY Machines
totally think you should wait. I have the Ormerod sensor on the way already, and that will work fine as I dial in the printer. it is also pretty small it looks like.by patrickrio - CoreXY Machines
ok, good to know. I will still be interested in your mini sensor when you do the next run... and i think i have two others interested too.by patrickrio - CoreXY Machines
Hi Dc42. I understand that you had your fingers on the infra red sensor on the Ormeron 2 also. That sensor turns out to be available now and can be shipped for $15 to New York. I ordered it. I may still order yours when you have it available too. How is yours different????by patrickrio - CoreXY Machines
Hey, could you maybe post a video of the sensor operating on a delta printer? Maybe one with your leveling start-up procedure in operation? It would give a good indication of functionality....by patrickrio - CoreXY Machines
I take it there are rules against listing prices???? the mini board is perfect... but they sold out pretty quick, last I asked, about 3 weeks ago, you didnt even have the empty pcbs yet!!! how do I get pricing? maybe I can get raw parts and solder up something temporary???? the weight is much better than the options for inductive.....by patrickrio - CoreXY Machines
Hi Dc42, I am now getting serious about choosing a proximity sensor for bed leveling. You mentioned your existing product with added bells and whistles. What are the measurements of that board? How much does it weigh? how much does it cost? Where are you on the miniature proximity sensing only board? when will that be done? what are its dimensions, how much will it weigh, how much will it cost?by patrickrio - CoreXY Machines
Hi Andrew, Did you ever get your extruder design posted somewhere? I think yours is the simplest, with the least amount of printed plastic, of any of the extruder designs... I would like to try it.by patrickrio - Delta Machines
I assume that I need some libriaries and sketches for the IDE, but I seem to be having problems finding them.by patrickrio - CoreXY Machines
OK, I have enough electronics here to do initial setup and testing. I have optical endstops connected to the duet, I have arduino IDE installed and am connected to the board. I have the fan, heated bed, and steppers. I have not updated firmware. Is there an installation guide for initial setup for a corexy duet?by patrickrio - CoreXY Machines
Parts are starting to arrive.... the last thing I ordered is the first to arrive... I now have a Duet control board, but nothing to control......by patrickrio - CoreXY Machines
how easy is it to start new filament with that design since it doesnt have a release lever.. is that what the key is for?by patrickrio - Delta Machines
I Have another candidate for extruder mechanism, from the delta printer page.... by AndrewBCN Pics of the design are here:by patrickrio - CoreXY Machines
what does the orange part do? I am going to use standard 90 degree metal mounting brackets for my motors since they cost almost nothing from robotdigg... stronger too.by patrickrio - Delta Machines
Thanks Dc42. Here in NYC, getting anyone to do anything for you besides telling you to f**k off costs more than it costs to order several perfectly sized Borosilicate glass beds from robotdigg.com Since I am waiting for parts now anyway, the glass can take it's time to arrive right to my dooooooor.... Still trying to figure out my options for the proximity sensor for nozzle height. Your lightby patrickrio - CoreXY Machines
Hi AndrewBCN, Have you uploaded the files for that minimalist extruder? Have you tried it yet? Do you have a picture of it assembled??? Here is the one I was looking at:by patrickrio - Delta Machines
I will be using z axis constructions similar to the attached files: what bed leveling construct should I use? I was thinking 3 point with 2 thumb screws, but is auto leveling an option??by patrickrio - CoreXY Machines
Hi, Dc42... you have been helping me a lot already in the other thread... I of course am going to be using your software and will help any way I can... in about a month when all my parts arrive!!!by patrickrio - CoreXY Machines
So, Dc42, I started ordering parts for setting up the head bed with aluminum... and I found that my heat bed already has an aluminum build plate that works as a heat spreader. They say that you can build strait on the anodized aluminum. In yur experience does this work? Or should I still buy the borosilicate glass?by patrickrio - CoreXY Machines
I am pretty sure that this motor and lead screw combo is WAY overkill for this application. I think that the smaller motor would have worked well for the z-axis since trapezoidal threads are MUCH more efficient at transferring torque to linear motion. If you think about it, it makes sense. BUT I have no experience in what happens real world in a 3D printer..... Normal machine screws are designeby patrickrio - CoreXY Machines
Here is a list of available metric trapezoidal lead screw threads.... notice the variety available for 8mm lead screws.by patrickrio - CoreXY Machines
This is the bowden extruder design I am leaning toward, mated with the E3D V6. If anyone has a better suggestion please let me know.by patrickrio - CoreXY Machines
Yes, 8mm diameter, 4mm per motor revolution. Other common sizes are 8x8, 8x12 and 8x20 Since I last said I was getting a somewhat underpowered stepper for my z axis, things have changed for the better. I found a NEMA 23 motor that has 62 oz inches and is only 30mm long. fits the space I have perfectly and has plenty of torque. It ended up costing me about 5 dollars more than the best price iby patrickrio - CoreXY Machines
OK, I am going to try this motor with 8x4 threads. If it fails, I am just out $27.... I think that going with the 24v power supply will also give me more Amperage headroom on this motor too.. right?by patrickrio - CoreXY Machines
Dc42, I am trying to understand the effect of threadrate. I am looking at the chart at and also so it appears that the Omerod has M5 threads, right??? On the Z-Axis with the same stepper motor as mine? So that would mean that if I got the same thread, my z axis would probably work fine with the same motor. Do you have any problems with z-axis speed?by patrickrio - CoreXY Machines
looks like I can get 8x1.5 threading also. better choice?by patrickrio - CoreXY Machines
for my lead screw, maybe I can just change the thread from 8x4 and get more force by increasing the revolutions for distance? I think I can have any standard thread made.... What thread would be good with this motor???by patrickrio - CoreXY Machines
figuring out the placement for filament spools.. what are the dimensions of the largest size of filament spool????by patrickrio - CoreXY Machines
Will this motor be good for the Z-axis???by patrickrio - CoreXY Machines
