Which controller should I buy to control Nema23 motors? - 3 years ago

Hi, I am planning to build a large 3D Printer using a CNC kit. The build volume is aroung 500mm x 500mm x 200mm. It will have 4 Nema23 motors, 2 Nema17 motors. Regards, Hughe

I'm looking for a fixed bed Cartesian 3D Printer to build. - 5 years ago

Hi there, I'm planning to build a large 3D Printer. The first prototype would have 300x300x300. The second one would be 500x500x500. I had built two Deltabot 3D Printers but due to space limitation I need to build Cartesian 3D Printers. I have three Prusa I3. I found one 3D Printer, which was Voron CoreXY 3D Printer. But new electronics and firmware put me back. It uses Raspberry Pi 3 B+,

Re: Extruder carried on 4th tower of delta (video) - 5 years ago

There is no new idea in the world! I thought shoter Bowden tube removes many problems caused by excessive bending of the tube during printing. I added the fourth axis to install the extruder on my Fisher last year. - Two smooth rods - Counter weight - Extra printed parts - Two pulleys - Two cylinderical bearings I haven't finished it though.

Re: Mechanical Rigidity Analysis of the Fisher Design - 6 years ago

@lkcl I upgraded the Fisher to laser cut 3mm to 5 mm steel plate. The problem I experinced was the failure of plastic parts that join the steel plates. Quotethat's why i pioneered the technique of quite literally making the frame from drinking straws, paper, cardboard and tape. it costs practically nothing, and can be done in about 20 minutes flat. you can then go, "hmmmm....", chuck it away,

Stand for Bookshelf speaker - 7 years ago

Hi, The stand is about 110cm tall which supports a 7 kg of speaker. The upper and lower plates are MDF. The pole is 26.5 mm steel tube painted in black. Original Prusa i3 MK2 1.75mm no-brand ABS filament OpenSCAD Slic3r Devuan GNU/Linux Link for the design file is It took about 10 hours to print the four parts. The bigger is the better.

Re: Time to move on? - 7 years ago

@cparsons I have a Original Prusa i3 MK2. It has five to eight minutes of warm-up time per each print. Swithing filament requires Z height adjustment that takes half to one hour for calibration. Total print time is 64 hours. I added 400x400x30 mm granite plate to reduce vibration and noise. I'll replace the spool holder to fix an issue. I've invested many hours on Steel Fisher. It's fas

PID auto tuning in RepRapFirmware dc42 1.17d - 7 years ago

Hi, I'm using a Duet 0.6 board, just upgraded the firmware to 1.17d. Fisher 3D Printer uses 19V, 60W hotend heater. When I ran M303 H1 P0.5 S260 for PID auto tuning, it overshooted temperature and failed. So I reduced PWM to 0.4 (40% of the maxium). I applied the PID values in config.g as below. ; M303 H1 P0.4 S260 ; (P0.5 Auto tune of heater 1 with P=0.50 S=260.0 cancelled ; because t

Re: mystery layer problems... - 7 years ago

@jimmyjim I'm glad to hear it was easy fix. Cracked idler. I replaced three original idlers with new ones a month ago. One night before yesterday Fisher was spitting filament in the air. I checked the cause yesteray and found two cracked carriages. Temporary fix using a ziptie. QuoteDADIY I've had all three happen to me and always recommend you print some spare printer parts in case

Re: mystery layer problems... - 7 years ago

Does the effector is firm without any freeplay when you wiggle it by hands? One pair of diagonal arm developed freeplay by loose nylon nuts. It occurred me once.

How can I use 0.2 mm or 0.25 mm nozzle? - 7 years ago

I checked two companies that sell Fisher parts. They only offer 0.4 mm nozzle for Fisher's Hotend. I have got no luck on eBay hunting.

Re: 3D Printing Newbie With a Fisher Delta - 7 years ago

@GreatOldOne I measured Fisher's power consumption to build a UPS. In idle Fisher takes 6 W to 7 W of power. During the heat up of hotend, it takes 60 W and then stays at 40 W for the whole printing session. I suggest you start printing while turning off the heated bed, then set the temperature of heated bed at 60 C in printing. If Fisher stops, you have a under rated power supply or fault

Re: Extruder idle lever tension - stops extruding - 8 years ago

@pixelseventy2 Set the current of extruder motor between 1000 (90% of maximum) to 1200, at 1000 mm/^2 acceleration.

If Fisher prints parts without failure, then you increase the retraction speed by few mm/s till printing quali

Re: Extruder idle lever tension - stops extruding - 8 years ago

@pixelseventy2 What type of extruder drive are you running? Fisher 1's extruder driver provides 3:1 gear ratio that has more torque than Beta's one. I replaced the stock extruder motor with 5:1 geared one because weak torque of the motor caused jamming two or three times in the past. Motor current and acceleration in config.g controls the motor torque also. Try Increase E### for extruder mo

Re: Non Squared Cubes - 8 years ago

When I printed a con model after six factor calibration, it printed the deformed con in rightside. I found it the six factor cablibration introduced excessive angle variation of towers which deform geometry of any model. To check the current delta configuration, run M665 in gcode console on DWC. The calibration assumes all 12 ball joints are square and in parallel, three towers are perpendic

Thanks.

Re: Is it possible to turn on and off the hotend fan? - 8 years ago

Fisher has one fan connected to F0 pins. It runs at constant speed until the power turns off. I also connected a 5V fan on the expansion pin to cool down the board. I like to know RepRapFirmware provide gcode commands that control the speed of two fans.

Re: Fisher heatbed - 8 years ago

Fisher has one heat sink fan that blows air into the fan duct. It's built for PLA. How do you guys print PLA and ABS alternatively?

Is it possible to turn on and off the hotend fan? - 8 years ago

Hi, I have a Duet v0.6 in Fisher. The firmware is RepRapFirmware-dc42 1.12a. I'd like to turn off the blower during the idle by creating two macros on DWC.

Re: What CAD software? POLL - 8 years ago

OpenSCAD. I only use QCAD to convert AutoCAD compatible DXF format. QuoteOpenscad is a cool tool, but it shouldn't be used if your goal is to design; it should only be used if your goal is to make something and it is your quickest path to that goal. IMO It is way more useful to learn a more robust CAD solution. I disagree. OpenSCAD is for hard-core users that want to produce 3D parts on demand.

Fail-safe tube fitting - 8 years ago
