SLA UV DLP 3d打印打印機(jī)，帶樹莓派

(update) Attached are some photos that helped me, voltages of stepper driver and UV lights and the wiring for the UV. And the nanodlp schematic and a video on a resin build plate leveling guide different printer same technique.. Also I used bike grease for the lead screw lithium grade 2. I have been asked for the vat to be printed as whole pieces for super large printe e.g CR10 S5, So here are the new vat files fused together and the UV tray. You need to cut and hot glue mirro onto the iide of the UV tray to direct the UV light directly to the LCD panel I used IKEA cardboard mirro. I used a dremel to cut them out.. When taking the backlight off of the LCD panel be careful not to damage the screen. There are to of videos on youtube about this topic. And only do this step at the very end of your printer build once you have nanodlp tested and set up on your raspberry pie.. . Also there is a piece of glass (larger than the UV tray sits over the top not touching the lcd panel) to be added above the lcd panel which can be sourced from a picture frame. This then has the edges taped with electrical tape to cushion the vat and protect the lcd panel Again this is the last step.. the glass on top will help level the bed here is a video on a smaller printer to help with leveling the bed skip to 2min 22sec Same process. minus the spring of coue we use leveling knobs which uses M8 bolts and nuts.... I have run out of funds now to fund this project I am working overtime to fund it. I will be able to do a build video when i can afford to finish this printer. I have a couple of make who are building this ahead of me and it is going well. To all you make out there enjoy this and please remix it and post makes and progress. I am just one peon who has given a base to build upon. if you downloaded an older arm print check the date and print the new one. not the old one. All open sourced. Also I have a plan in place to build large custom ultonic cleaner baths that use nice smelling cleaner and not IPA alcohol also on that note I will make a tube at the back that uses this tech Electrostatic Precipitatomoke Precipitator to reduce fumes. Also an auto refill seor for the resin straight from the bottle with a 12v pump.... Check out franky hu youtube to get wiring and operting tips for the printer (this will help you with the wiring) and trouble shooting check out his channel he has loads of videos to calibrate the printer also bear with him his english is a little rusty. He is the supplier. For the eletronics. I will be doing a step by step setup video soon Here is the custom nano dlp img franky uses And pdf for the nano dlp sheild Resin exposure settings for most resi Update BOM list 1pc Hybrid Nema17 bipolar step stepper motor 1.7A 38mm length 35Ncm 4 leads 42SHD0112-24B for RepRap 3D printer 1pc 100x100x1mm LED GPU IC Chipset Heatsink Cooling Silicone Thermal Pad Double-sided adhesive The photoseitive SLA 3D printer supplies accessories FEP film high accuracy DLP 0.15 thickness 400mm x 500mm x 0.15 12V6A New AC 100V-240V 72W Converter power Adapter DC 12V 6A Power Supply EU/US/UK Plug DC 1pc 3D Printer Cooling Fan 404010mm 12/24V 0.1A With 2 Pin Dupont Wire For 3D Printer J-head Hotend 3D Printer T8 Rod Screw OD 8mm Pitch 2mm Lead 2mm Multi Sizes (350mm) Threaded Rods with Brass Nut for Z Axis Used the same but longer (350mm) (for the vat) used the same design but way way bigger 4pcs/lot 10W UV Lamp 395NM/405NM Purple COB LED Bead Light High Power DIY Ultraviolet LED (i used the same but longer chose 350mm L) same heat sink 2pcs LM8LUU Linear Ball Bearing 1pc Ball Bearing 608 1pc Shaft Coupling 5X8 1pcs 300W Boost Converter DC-DC 7-40V to 0.8-35V 9A(MAX) 0.2-9A adjustable Step Up Voltage Charger Module XL4016 (same nanodlp board) With A4988 (update I would recommend replacing the stepper motor driver on the board with an official one from your local hobby store or electronic supplier online that is what I have just done after reading up on it in forums) The good thing is this nanodlp sheild comes pre soldered (touchscreen board for the front) FEP film for the vat 2k panel 4k panel Mini hdmi adapter to hdmi And a rasberry pie.
