The Digital Dentist, what did you end up doing about driving the rhino stepper? Did you use the nema23 that came with it? What kind of driver did you use? I am planning to use a suite wifi which allows 2amps to the motor nvm, found it. Quotethe_digital_dentist The stepper that came on the Rino is a 166 oz-in NEMA-23 motor, but with 30:1 reduction / torque multiplication, I think a NEMA-17 motoby Qdeathstar - CoreXY Machines
who knows! I've got to rework the z axis, complete the wiring, and it should be ready to print. maybe before winter is over...by Qdeathstar - CoreXY Machines
Been a long while since I had a proper update. I can't believe it has taken this long to get the xy assembly right again, but other projects pop up... anyway, some pics: This is one of the belt clamp for the effector, I machined it down to match the bearings, then notched out s bits round the corners so the belts had a place to lay, than drill/tapped a few holes to get everything to stay in plby Qdeathstar - CoreXY Machines

Quotegromyjoe So I was watching this video on YouTube and it made me wonder if something similar could be incorporated into 3d printers. It is called a resolver, similar to an encoder but it is more accurate and can remember it's position after it loses power! The guy explains it in much better detail than I could so here's the link Would it be possible to use something similar on the oppositeby Qdeathstar - Delta Machines
Here is an update This is the mount for the idler pulleys. I was using printed abs but after a month of tension in the belt the abs want really holding up, plus, i had to use long screws because the abs was thick... A view from underneath, showing some pocketed fasteners. This is the base of the motor mounts. The slots are to allow sideways adjustment of the motor, so that i can keepby Qdeathstar - CoreXY Machines

What size tubing are you using for the two titan extruders?by Qdeathstar - CoreXY Machines
It has power feed on the x-axis, I plan to add power downfeed on the head (not the spindle), I am currently working on installing dro. I don't think milling is very popular around here, there was nothing for sale except rust-bucket machines locally, though I expect that may have to do with the fact that most of the population is transient ( 4 larger military bases within 20 miles of me) and the fby Qdeathstar - CoreXY Machines
Saftey third! I'm getting my milling machine honed in (got to install the dro) and once it is done back to the core xy. I like the covers, but you should have made them with t-glaseby Qdeathstar - CoreXY Machines
Quotedougal1957 QuoteQdeathstar ah. I'm curious about it, where is it on the pcb? Could you take a pic Picture of what exactly? if you mean the strain gauges then they are actually designed into the PCB Traces so not much to be seen on a photo (They can be seen as very fine traces in the copper by eye but they don't show up well on photos) Oh, ok. I didn't know they were printed on, that's prby Qdeathstar - Delta Machines
there are some people who won't accept less than a full sized knee mill from bridgeport or one of the other non-chinese companies. Im not an expert, but judging from what i've done thus far it's a capable machine. I mean, yeah, if you got room and money for a bridgeport go for it. A working bridgeport goes for around 4500 without tooling, and you need some heavy equipment to move it in to a newlyby Qdeathstar - CoreXY Machines

Quotedc42 You are both wrong, it's a strain gauge. what kind of IC is it?by Qdeathstar - Delta Machines
I think it is an accelerometer and not a piezo... maybe wrong thoby Qdeathstar - Delta Machines
Sending you a working ramps config won't tell you much because it would work for my printer but not for yours. The ramps board has little stepper motor driver breakout boards that plug into the board, I assume you have these plugged in and have adjusted the little pot to increase the current to the steppers. Also, issue command M119 to check the status of your end stops, to make sure they aren'by Qdeathstar - CoreXY Machines
Finally got the mill home and in place. I still have a lot of set up to do. I need to extend an existing 20amp 240v circuit so I can power the thing... and need to install the digital read out. The mill and stand weighs around 1000lbs .by Qdeathstar - CoreXY Machines
Hi, I did not see the replies till now. Most 3D printers take more than they give, be prepared. So, it is not a temperature issue, Have you printed a test cube? eg, not that specific model, It is also possible that there is an issue with the model. Maybe try to print Melvin at 2x scale, you can find him on thingiverse.com Maybe you are retracting too much, Set your retraction to 0. YES, youby Qdeathstar - Delta Machines
my mill is sitting at my office waiting to be brought home... then, back to the 3d printer.... Hopefully i get the mill up this weekendby Qdeathstar - CoreXY Machines
If your trying to build a top end 3dprinter don't skimp on the electronics. I have the Duet Wifi and could not be happier. I can't imaging building another printer without purchasing a DuetWfif. If your trying to save a bit of money, you can skip out on the Panel Due as the web interface that comes with the DuetWifi works seamlessly.by Qdeathstar - Delta Machines
yes, i made a waterblock for my cyclops exrruder... the enclosure at 50c caused heat creep with just the fan, and i would get partial clogs.... no moreby Qdeathstar - CoreXY Machines
Nothing too fancy... i used some thermal epoxy to glue the heat sink to the motor housing. It's surprising how well it works despite the small contact surface area. The motor was hot to the touch without the heat sink and fan, with it it is barely warm.by Qdeathstar - CoreXY Machines
Quote That motor has phosphor bronze brushes like a cheap toy. It isn't designed to operate for more than a few hours because the brushes wear out and can't be replaced. I'd also be surprised if it can operate for more than a few minutes at "rated voltage" without burning itself up. OTOH, maybe the bronze bushings will wear out before the brushes. The berdAir uses that same motor and I've had noby Qdeathstar - CoreXY Machines
i think you should try lowering the bed temp after the first few layers....i had an issue like this and the heat bed was too hot and caused distortion,by Qdeathstar - Printing
It sort of looks like your extrusion width is set funny, did you change it or did you let the slicer choose? Are you sure you have your nozzle size correct. It looks like your printer has a bad calibration, a hair low in some places, and high in other.by Qdeathstar - Delta Machines
Look at the digital dentists topic. It contained enough pictures and information to work as a plan. I am building one now using his topic as a design.by Qdeathstar - CoreXY Machines
Lars, did you buy the pipes from makerhive or did you make you own? Can you post pictures of the pipes and how you bent them? I like the effectiveness of the berdAir (a system like you have) but the pipes that come with it i find are difficult to bend just right..by Qdeathstar - CoreXY Machines
The machine comes with a vfd to convert single phase into three phase... i do have a shop with three phase service, but i want this close to homeby Qdeathstar - CoreXY Machines
