Re: Cad for printing...?? Moving On? - 4 years ago
I have ended up using OpenSCAD for everything I do these days. It's free, very powerful, but there are down-sides. First, a background in some form of programming is a major advantage to get the structure of the code correct. This includes stuff like matching parentheses, variable scope, etc. I have written some form of code all my working life, from LaTeX word processing, HTML, Pascal, C, Cby David J - General

Re: Could use some help with step calculations - 5 years ago
Delta settings were auto-calibrated, but that doesn't mean that they're correct! I'm using eSun PLA+ but I don't know if I need to allow for shrinkage with this material (I must admit that's not a factor I'd considered...) UPDATE: Just did a quick Google on PLA shrinkage - apparently it's 2.0 to 2.5%, so that is starting to match my results... maybe in the future I will just have to add a 'shriby David J - Firmware - Marlin
Could use some help with step calculations - 5 years ago
I have an Anycubic Kossel Linear Plus, with Marlin 1.1.9 loaded. The steps/mm is now calculated as follows: // variables to calculate steps #define XYZ_FULL_STEPS_PER_ROTATION 200 // These are the setting for the stock Stepper Motors, pulleys and Belts on the AnyCubic Kossel #define XYZ_MICROSTEPS 16 #define XYZ_BELT_PITCH 2 #define XYZ_PULLEY_TEETH 20 // delta speeds must be the same on xyz #by David J - Firmware - Marlin
Re: Pronterface gets hung up when connecting, MKS SBase 1.3 Marlin 2.0 - 5 years ago
Ah - my error. It was pure coincidence that the symptoms were so similar! However, I have gained from this dialogue, even if Hugo has not (sorry, Hugo) - I now know that I can connect properly if I click on the Reset button in Pronterface. Thanks to Dust for putting me in my place very politely, as I have been on other forums where such a mistake would have earned someone's great wrath! Cheby David J - Printrun/Pronterface

Re: Pronterface gets hung up when connecting, MKS SBase 1.3 Marlin 2.0 - 5 years ago
QuoteDust Did you set a serial port to -1 in your Configuration.h? As -1 is serial over USB Also with this type of serial over USB, Baud rates are ignored. So that isn't the problem. You also say the computer identifies the board as marlin?? well it shouldn't, it only turns up as a serial port and a usb drive.

Here's what finally got me there: go into Settings -> Options -> Printer settings tab. Try setting TCP Streaming mode, RPC Server, and DTR to false (the last 2 are true by default). In my case, if any of these three were set to true I couldn't make a proper connection. It may not work in your situation, but anything's worth a try!by David J - Printrun/Pronterface
Re: Placing objects on the bed of a delta in Pronterface - having problems. [SOLVED] - 5 years ago
Thank you so much! A simple omission on my behalf, but it now works correctly. Setting the X- and Y-Home positions to the same value also stopped the effector trying to push its way through the X column at the end of the job... Davidby David J - Printrun/Pronterface

Placing objects on the bed of a delta in Pronterface - having problems. [SOLVED] - 5 years ago
Machine: Anycubic Kossel Linear Plus I have finally managed to get the motherboard to talk to Pronterface, and I can send G-codes to interact with the printer. All good so far. Repetier-Host and Cura can both send G-code to the printer and print them properly, so there's no fundamental problem with either the printer or its communications. Pronterface insists on placing newly loaded G-code filby David J - Printrun/Pronterface

Unfortunately the reset button is hidden deep in the bowels of the delta printer... Oops! I just watched the video - I was thinking of the wrong "reset" button! (I'm on Linux, BTW.)by David J - Printrun/Pronterface

I have an identical problem with my Anycubic Kossel Linear Plus (Trigorilla board) after updating to Marlin 1.1.9. However, it works perfectly with Repetier-Host. Both have the correct settings (I believe). I'll be following this topic with interest!by David J - Printrun/Pronterface

Delta homing under Marlin - moved from 'Deltas' - 5 years ago
I moved this problem from 'Deltas' to here are it's more of a Marlin issue than specifically with the machine itself. I have a fairly new Anycubic Kossel Linear Plus running Marlin 1.1.9 (recently updated) on its TriGorilla board. Everything is going well, and I'm getting decent prints. However, I have one significant problem: when I'm doing the Delta Calibration routines via the LCD, the printby David J - Firmware - Marlin
Odd problem with Trigorilla board and Pronterface - 5 years ago
Summary: I have recently built an Anycubic Kossel Linear Plus delta - it works 100% with Repetier-Host, but fails to connect with Pronterface. History: When I first got this machine it showed up on my Linux system as /dev/ttyACM0, and Pronterface had no difficulty connecting to it. Unfortunately the version of Marlin that was pre-loaded on the board was useless at auto-calibration, so I upgraby David J - Controllers
Re: Excessive Hotend Jams - 5 years ago
QuoteTempest815 I'll try replacing the nozzle and maybe the heatbreak and see. I think theres a jam in there now anyway. I'm going to get genuine E3D stuff. Is titanium worth it for the heatbreak? I have genuine E3D v6 on 2 of my printers, both with the standard heatbreak - the only time I get a jam is when I do something really stupid.

Re: An alternative to buying a bad kit for $300-500 - 5 years ago
You could try heating up a large lump of metal up to red-hot and just touching it to the head of the screw for a few seconds - sometimes the sudden expansion and subsequent contraction can free off a screw. Maybe.by David J - General
Re: Extruder completely clogges after only seconds of use - 5 years ago
The E3D v6 doesn't like big retracts - I set mine to 2.5mm @ 40mm/sec. Any longer and you risk pulling the hot and soft filament into the cold area, where it sets.by David J - Printing
Re: Good hairspray for the print bed in the UK? - 5 years ago
QuoteOhmarinus Ohhh my bad, sorry. It's this stuff: It's from Spain, we use it at the academy where I work on the 3D printers. This stuff is unstoppable. I take it back - I just looked it up on Google and it is available in the UK... at £7 - £11 a can! The exchange rate is almost 1 EUR to 1 GBP at the moment. My can of Elnett was £3.50 for 300ml.by David J - General

Re: Good hairspray for the print bed in the UK? - 5 years ago
I can now confirm that "L'Oreal Elnett Extra Strong Hold" works just as well as Sainsburys Basic hairspray! I bought a can today and tried it this evening - just the right amount of sticking on glass for PLA (not tried it with ABS yet). The room now smells like a tart's boudoir though...

Re: Good hairspray for the print bed in the UK? - 5 years ago

Good hairspray for the print bed in the UK? - 5 years ago
For the past year or three I've been using Sainsburys Basic hairspray on the heated glass beds of my printers, with a lot of success. Apart from working well, it was ludicrously cheap - under 50p (less than 1$) for a 300ml can. My problem is that I've run out... and Sainsburys don't sell it any more. I've tried Tesco Essentials hairspray (ridiculously expensive at 79p for 400ml!) but that's jby David J - General
