Arduino + Ramps + LCD - 9 years ago
Hello everyone. I want to make my 3d priter to run without USB conenction, only with powering my power supply. However, when i connect power supply without usb in my pc, LCD just lights all its pixels and wont work. It seems that arduino wont get needed 5 Volts. My diode D1 on RAMPS is installed. What is the solution without powering arduino with 5Volts externally? Thanks BTW: my 5Volt regulatorby Capinho - Printing
Re: Blobs - 10 years ago
My stepper motor cant reach such high speeds, it stutters when speed is set higher than 75 mm/sby Capinho - Printing
Re: Blobs - 10 years ago
Quotedc42 Your image link doesn't work so I can't see your settings. I am using an E3Dv6 with a 600mm long Bowden tube, and I need 8mm retraction to avoid blobs. 6mm was not enough. Fixed. What are your retraction speed settings?by Capinho - Printing
Blobs - 10 years ago
Hi everyone, I have perfect surface quality prints, except blobs on retraction spots. I am using e3d v6 bowden, tube is about 450-500mm, retraction settings: I am using simplify3d software. Extruder is direct drive mk8 gear. Any suggestions how to get those blobs gone? Thanksby Capinho - Printing

Geared stepper retraction problems - 10 years ago
Hello everyone, I have purchased 5:1 geared stepper motor, 0.4A, and i cant get my retraction working at all. I guess it will have something to do with acceleration etc. When i set my retraction to like 5mm ant 65mm/s, motor just hops back a little, like half of mm retraction of filament. It seems it has no power or can't reach such high speeds/distances. Can anyone help me to sort this out? Thaby Capinho - Printing
Best filament in Europe? - 10 years ago
Hello everyone, I am looking for new filament supplier in Europe. What filament are you guys using that is cheap and good quality? I would be very thankful if all of you shared your filament suplliers. Thanksby Capinho - General
Re: Geared stepper for extruder - 10 years ago
Quotedc42 A small amount of backlash in the extruder drive shouldn't matter, it just means you may need up to 0.1mm more retraction in your slicer settings to allow for it. Does that mean, that I need 0.1mm more retraction while pulling up the filament and extra 0.1mm while releasing it?by Capinho - General
Geared stepper for extruder - 10 years ago
Hello everyone, I need to buy geared nema17 stepper to have stronger extruder, because my stock one is too weak to feed the filament through bowden tube. I have almost purchased this stepper, but i saw the note, saying : Please note, this planetary gearbox is not high precision gearbox, the backlash we can promised is <=1 degree. Is this stepper precise enough for using it as extruder motby Capinho - General
Re: CoreXY questions - 10 years ago
QuotefilipeCampos I have build an corexy using 20x20, the size of the printer is 40x40x52 cm. I have used 4 bars 20x20 for each side, two of this bars are very close of the corexy mechanism. Was result the structure of the printer is very rigid and i can say is overkill. For your case it will sure work very well. You can use 20x40 instead of 2 bars 20x20 , the price will be almost the same. Theby Capinho - CoreXY Machines
CoreXY questions - 10 years ago
Hello everyone. I have started thinking about building my new machine with CoreXY kinematics, and build volume 400x400x400mm. I am thiking about box frame made out of 2020 aluminum extrusions. Estimated frame box size would be 600x600x600mm or so. I will be using bowden extruder, Hiwin MGN12 rails and carriages for motion. My main question would be if the frame is sturdy enough for my machine? Oby Capinho - CoreXY Machines
Fan duct for kossel mini - 10 years ago
Hey everyone. I have just finished my Mini kossel, but I lack of proper cooling. I want a fan duct that cools all area around the nozzle.

Re: AISI 304 steel smooth rods - 10 years ago
Quotecdru What type of bearings are you using? And what are the tolerances of the rods that you're using? I'd say that is just as important if not more important than just the hardness. And what country are you in? There's a global marketplace out there you know... I will use LM8UU bearings, shaft tolerances are h9. About global marketplace, shipping prices exceed actual smooth rod's price up tby Capinho - General

Auto bed leveling servo angle problem - 10 years ago
Hello everyone. Recently i have installed auto bed leveling on my Velleman K8200 (3drag). Everything was working fine, until I accidentaly broke my servo. After replacing the servo with new one (Tower pro 9g), servo moves only to one position, does not matter what angle i send with M280. It always goes to the same angle, despite the angle. What could be wrong here? I have checked my wiring, pinsby Capinho - Printing
Re: Homing/endstop problems - 10 years ago
QuoteKafledelius The logic of the endstops are inverted. Have you tried removing that ? Edit the following lines const bool X_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop. const bool Y_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop. const bool Z_MIN_ENDSTOP_INVERTING = true; // set to true to invert the logic of the endstop. toby Capinho - Printing
Re: Homing/endstop problems - 10 years ago
Quotemandrav Did you check M119's output while manually triggering the endstops? Is their state changing appropriately? Also, check that you 've actually wired them to the min endstop pins. I had this happen once when I wired the endstop to the max endstop pins by mistake. Yes, while cheking M119, endstop's state changes manually pressing it. And yes, they are wired to min pins.by Capinho - Printing
Homing/endstop problems - 10 years ago
Hello everyone, i am facing issue with my prusa i3. I have Mechanical endstops V1.2. It triggers open/close normally, as it should. (opened, when not triggered, closed, when triggered). However, when axis is homing, when endstop is pressed, axis gets no reaction at all, and it keeps hitting the endstop. What could be the issue? I am using Marlin software. Marlin code is shown below. //=========by Capinho - Printing

Extruder motor wont turn with g code, but works manually - 10 years ago
Hello everyone. Issues with my extruder wont stop. Extruder motor works manually, but wont work with G code. I dont know, whats wrong. Currently I set my max feedrate to 5 mm/s and it wont work. Here is a piece of my g code: G21 ; set units to millimeters M190 S50 ; wait for bed temperature to be reached G28 ; home all axes G90 ; use absolute coordinates G21 ; set units to millimeters G92 E0 Mby Capinho - Printing
Re: Filament slipping - 10 years ago
Okay, I have just checked in my Marlin software, the parameter is Maximum feedrate. How to change the feedrate of the repetier buttons, so I can adjust the actual feedrate, not the maximum? New question, do I have to define microstepping somewhere or is it enough just to have jumper pins installed? Thanksby Capinho - General
Re: Filament slipping - 10 years ago
My feedrate for extruder is set to 50 mm/s in Marlin software. My nozzle is 0.4mm atm, at first I had 0.25 mm. My bowden tube is about 50 cm long. Skipping might be appearing when i thightened bearing all the way possibleby Capinho - General
Re: Filament slipping - 10 years ago
I have changed the bearing, changed the gear, made temperature higher (230 degrees). Results are a bit better, but still pretty much the same issue. here is a videoby Capinho - General
Re: Filament slipping - 11 years ago
I am so frustrated right now. I have tried changing plastics and everything, it seems to be problem with the hotend, because it works perfectly until the filament reaches the hotend. Could my stepper motor be too weak? I am using stepper of holding torque 4000 g*cmby Capinho - General
Re: Filament slipping - 11 years ago
Ok, i mounted a new bearing and apparently it was not the bearing. I also noticed, that this slipping occurs only when the filamend reaches the hotend, until then - it runs smoothly. I have also removed 3rd jumper from my Ramps board, so now i have 1/8th microstepping only. Whats the issue? Jammed hotend? Not enought motor power? Too small nozzle (0.25mm)?
