Has anyone experience with TMC 2130 drivers on a Rumba board? I watched Tom's video on the TMC 2130 and how to hook up to Ramps. But not sure how to apply it to my Rumba. Found a Rumba on Ebay with standard mounting.by RodF - RAMPS Electronics

Hi Mark what is UMMD? How are you going with the Volcano. I am running one with .8mm nozzle. Setting the slicer (Slic3r) extrusion level is quite critical for me. Rodby RodF - CoreXY Machines
I have installed the Panel Due. It was plug and play. I had some difficulty printing the large enclosure for it in ABS with the .8mm volcano nozzle. Thanks to Azerate over on Soliforum for slicer settings I ended up with a good result.by RodF - CoreXY Machines
I really like the WiFi interface, but at work it is an issue with range and security (dealing with the IT dept.) So I am interested to see how the PanelDue works out.by RodF - CoreXY Machines
QuoteQdeathstar Hi, I am looking to build a core XY using this design: I have a few questions. 1) It uses printed parts for the frame. Are their suitable metal corners that I could use instead, and are they worth the extra cost? I know for delta's getting the frame right is crucial. I also see that it uses cheap bearings with deldrin wheels. However, the open builds store offers premium pby RodF - CoreXY Machines
I have got the machine at work now. However it's in a steel container and Wifi is an issue. So I have ordered a PanelDue for it not sure where it will get mounted yet. While I wait for that, I am going to upgrade my cartesian machine with a Smoothie board I had originally planned to put in the corexyz.by RodF - CoreXY Machines
QuoteKewtdz Very impressive build. How are you liking the PrintBite surface? It seems to be working well on that ABS Polycarbonate, did you have to do any prep? Cheers, the machine is running nicely now but I wish I had more time to explore Duetwifi. The ABS poly carbonate is sticking to the printbite really well with no prep required. I started with 135C bed temperature but have been able toby RodF - CoreXY Machines
Hi Napierm My system of setting up the 2 rails is to tighten one rail, hopefully straight and perpendicular etc. Then run the carriage along it tightening the other rail as you go. This has worked for me up to 1 meter. If it is not working look for the rails not being on the same plane or the carriage twisted. An option if all else fails might be to rubber mount one rail so it can move slightlyby RodF - CoreXY Machines
I have been working at tuning the machine. I have decided to get it printing with ABS Polycarbonate (from E3D). 280C nozzle 135C bed, it is over-extruding in spite of carefully calibrating the extruder. The prints are sticking to the printbite really well and the over-extruding is at least filling the print solidly. The parts are slightly flexible and incredibly tough. The heated bed is heatiby RodF - CoreXY Machines
Hi theory Nice machine, well done. To achieve equal belt tension I use pitch (musical). Choose the 2 shortest equal length belt runs and ping them, adjust the tension of one of them till the pitch is the same. Much easier if you have screw adjustment. If you are tone deaf use a guitar tuning app on your phone. Check to make sure your belt runs are co-linear parallel and perpendicular, if not teby RodF - CoreXY Machines
Got the door hinged latched and sealed. I will probably order a U shaped heater of 800W. Don't want much more than that as the bed heater is 750W. I will probably duct it and run a fan.by RodF - CoreXY Machines

Quoten9jcv kd6hq Thanks for the comments. I really dont see a big deal with 2 z steppers. I have an I3, running for 2 years and it has never gotten out of level. The steppers always seem to be in sync. Once leveled it is done for me. I don't use autobed leveling, just did it once very well and used bolts and nuts to secure and from there it holds. Mind you it would get out of sync if somby RodF - CoreXY Machines
Quotethe_digital_dentist Noice! Will you be adding an enclosure heater? Yes that would be nice. I haven't seen any setups for a dedicated enclosure heater so I have made no provision for one. At this stage I was hoping the bed heater would do the trick. I have some colour controllable LED strip which I would like to use as temperature indicator and lighting.

I weighed the machine today and it is 22.9 kg at the moment. So it will go a bit over 23kg. A bit of a lift but manageable. I made a short videoby RodF - CoreXY Machines
Quotethe_digital_dentist Any idea how much it weighs? How are you sending files to it to print? I will weigh it today. It is a one person lift although a bit awkward so I am going to put lift handles on it. I have quite a few prints now. I have only used the Wifi for control and I really like the web interface.

After using the machine for a few weeks I decided to make a new extruder mounting plate. Now I can take off the extruder assembly simply by removing 2 screws and unplugging the wiring. Have also incorporated a mounting system for a print cooling fan and shroud. The extruded plastic coming out of the .8mm nozzle really retains it's heat so small parts of the print stay very soft unless I go realby RodF - CoreXY Machines

Not much work on the machine as I have been printing with it. I want to get the machine enclosed so I can try printing ABS-PC. I put a sheet of clear poly-carbonate on the base along with some rubber feet.by RodF - CoreXY Machines
Ok ladies and gentlemen here's my 2cents. Complete designs with cut lists, BOM's and assembly instructions are pretty much non existent or if they are they aren't what you want. CoreXY is the design, so all you are doing is sorting out how to hold the bits together to make the design work. Make a list of features for your machine. Variables. Frame construction. Flat panel or extrusion. Motiby RodF - CoreXY Machines
Ummm on closer examination it seems I had forgotten to tighten the screws holding the rails to the 2020 frame. So the bed had been essentially floating on the screws. Much better now, but it will still get the ACP on the back.by RodF - CoreXY Machines
You are best to get the right motors for the job. 0.9 degree for XY, a good powerful ( 2-2.4 amp) motor for Z and a lightweight nema 17 for the extruder. Stepper online have them and they will only cost a few dollars more than the ones you linked to. Get a 32 bit controller, the cheapest run Smoothieware.

Quotethe_digital_dentist Check squareness by measuring diagonals of the squares in each plane. If they match, the axes are square (for that plane). Is the bed heated, and are you using PID control or bang-bang? Those Z artifacts could be caused by bed temperature variations. Unfortunately due to warpage on this part measuring the diagonals is not a reliable test so I am using this dial angleby RodF - CoreXY Machines
