Using timers/delays in the firmware to change "configuration" parameters - 5 years ago

Hello all, I was wondering if there is anyone that has experience implementing delay/timer functions to modify Marlin code, specifically in 'configuration.h"?? I would like to say, after 100000ms after the board being turned on, to change parameters in the Marlin code e.g. stepper motor direction. Unfortunately, when I try to compile marlin with blank void setup (){} and void loop (){} calls t

Hello Geoff, There is actually a hackerspace in Ipswich with fellow 3D Printing enthusiasts that should be able to help you: Otherwise Hackerspace Brisbane will also be of great help to you, there's definitely people with Prusa i3's around when I last visited: Regards, DennyP

Re: Aussie keen to join the 3D printing party! Leaning to Prusa i3. Advice please - 8 years ago

Hello Jay_Z_ I'm a fellow Aussie (Sydney). I do recommend the self built approach of the Prusa i3, which is a tried and true design in itself. The Prusa i3 variant I would recommend (and currently building right now) is the P3Steel: With your background, you might be able to have access to a laser cutter to do the frame for you, otherwise I can forward you details of the laser cutter company

Re: Help Print Rite DIY Printer - 8 years ago

Hello cYbja That G1 E-0.60000 F1800.00000 "looks" like it's a retraction code indicated by the minus sign behind 0.6. E signifies that this is command is for the extruder (you have X, Y, Z in addition), while F indicates the feedrate. If my units are correct, based on , this line is retracting 0.6mm of filament at a feedrate of 1800mm/s (this would be exact assuming you've calibrated your steps_

Re: Is there anybody out there? - 8 years ago

Hello again Daggs, Great minds think alike! That's strange, about how all the different software deals with the same .stl, but nothing suprising. I think with open source software, esp two different brands doing the same thing, will do things differently as there isn't really a set standard to do things out there in my opinion. We've both experenced that! I had the same experence with slic3r

Re: Is there anybody out there? - 8 years ago

There are probably ones out there using a 3mm thread. You could use a compression spring + washers to stabilise the M3 screw with a washer and a M3 nut or better, a locknut to hold it onto the printed part like shown here: Another idea is to actually cut a hole in the stl between the screwhole in the part and slide an M3 nut that's secure in the part itself to act as a lock. Threadlocker will

Re: Is there anybody out there? - 8 years ago

Hello Daggs, What is the wattage of your power supply? it could be underpowered. What is the resistance of your heated bed, it might be too high of a resistance. Here are some resistances for reference, if you have a multimeter it would be a worthwhile check: It's strange that an aluminium bed would take that long? Unless the aluminium heated bed in theory would have a higher thermal conducti

Hey Daggs, I was also cut that the Sharks didn't make it, but atleast the Bulldogs didn't go through! (Parra supporter here). Ah never thought you were ignorning my advice, just keen to try to assist you. I know the pains of starting with a open-source printer, especially when there seems to be not many of us in Sydney to refer to. The hotend seems definitely too high above the glass plate if

Re: Is there anybody out there? - 9 years ago

Hello Daggs, The Rostock utilizes the alternative kinematics called Delta, and it's exactly as you described: dependant vertical axes moving simultaneously together to move the hot-end to a definite 3D location using diagonal rods. it uses some trigonometric calculations to do it. You can drive a delta printer faster more confidently because the hot-end is positioned on a light platform called

Hello, I'm here! I'm based in Glenwood. I've done a Rostock build that took me 5 months to gradually build up and absorb all the open-source information out there: was a fun, interesting, sometimes frustrating journey but all rewarding in the end.

Re: The Delta Steel, a slightly modified Delta-Pi - 9 years ago

Hello Andrew, What's the Torsional strength like with this machine? It certainly looks torsionally stronger than the original Rostock because I would think it's a lot harder to twist 20mm square tubes around itself than 8mm rods. Also noticed the MDF backplate, that would add strength too. Also I could print the structural printed parts with a 100% fill to make it as strong as possible. Cheers

Re: RUG/Australia/Sydney - 9 years ago

Hello Eddie, There are definitely quality variations between manufacturers and suppliers. I haven't had much experience with many different brands, but I have had the best success with Lybina/Plastrude. The owner knows the importance of Polymer quality for 3D printing. You can get Lybina PLA roll from Robodojo near Campbelltown and they might sell ABS too.
