Re: Marlin needs your help to go 32Bit - 5 years ago
Well try G1 X 100 F1 and listen if the microstepping works. See for the reason it doesn't and the simple fix. This problem was well known in the RepRap world after my article so I was surprised to get a Smoothieboard with Rosc = 10K and found it ironic. I stopped following on github, and it may have been two years ago, but at that point I read that the ADC produces bum samples of 0 or FFF due tby nophead - General

Marlin already runs on 32 bit platforms, see , so I don't see why any money is required. Get ST's version.by nophead - General
Re: SKEINFORGE manuals suddenly disappeared - 5 years ago
I have occasionally tried others but never got the right dimensions, so I stick with Skeinforge. I will write my own slicer one day!by nophead - Mendel90
Re: SKEINFORGE manuals suddenly disappeared - 5 years ago
I emailed the author, Enrique Perez, about it in Feb. He said he would ask Bogdan Kecman slowly to sort it (I think it must be his server) but nothing seems to have happened. There is a copy of the documentation in the Skeinforge folder, not as good as the Wiki version. You can view the Wiki version with the Wayback Machine, but it is a bit slow: .by nophead - Mendel90
Re: Original Nophead Firmware - 5 years ago
You should be using the Melzi BSP, not gen7. I think gen7 runs at 20mHz.by nophead - Mendel90
Re: Original Nophead Firmware - 5 years ago
I use anything between 1.0.0 and 1.0.5. I don't think my fork of Marlin even complies with 1.5.x, so I don't see how you managed to use that.by nophead - Mendel90
Re: Original Nophead Firmware - 5 years ago
It makes no sense to because the firmware has never changed in that respect. The my version on github has very few changes and works on all the boards we sold and also on a Melzi v2. Presumably the hex file you have is just an older version of what is on github? You can look at the commit list and see there were no changes to the I/O throughout Mendel90 kit production. Is is possible you have a dby nophead - Mendel90

Are you sure you have wired the bed and fan to the correct terminals?by nophead - Mendel90
Re: Original Nophead Firmware - 5 years ago
There are no differences firmware wise between the Melzi we supplied and the Melzi V2, as supplied by RepRapPro. I recently tested a Melzi V2 with the original firmware, so I can't explain your symptoms. The bed MOFSET does get very hot because the ground track leading to it is very thin, the main ground plane has been isolated by a new track running through it. It needs bridging with a wire.by nophead - Mendel90
Re: Help with first-time setup! - 5 years ago
If you are not familiar with the settings by far the easiest way to set it up is to use Neil's version of Marlin and change the board definition to Azteeg. No you don't need to manually home the machine before powering it up. Just make sure the X carriage is not on the far left. You can then home with the host and your slicer's start.gcode should contain a homing sequence so it homes before everby nophead - Mendel90
Re: Help with first-time setup! - 5 years ago
Quote.Jata I don't mind it either way then. It just seemed like I was doing something wrong! lol Would you recommend 1/16 or less? Thanks! I can only recommend 16 because that is the only setting I have tried with Mendel90. More microsteps will be quieter but the top speed will be less. Also a lot of boards have this problem , which I fixed on the Melzis for the kits: .by nophead - Mendel90
Re: Flexidrive is Flex3Drive Early Birds - 5 years ago
Quoteslanwar I used 3M 468MP high temperature adhesive transfer tape, hard to use as hell, tried to use the entire sheet so would cover the PEI but end up cutting small strips. Great, I have a reel of that 20mm wide.by nophead - General
Re: Help with first-time setup! - 5 years ago
Normal configuration for Mendel90 is X and Y are min and Z is max. That is conventional when viewed from the back. If you want it conventional from the front then make them all max. See for the rational for Z max. See the manual for how to calibrate Z without running the head into the glass. Setting the microstepping bigger than 16 may limit your top speed with an Atmega. I haven't tried it.by nophead - Mendel90

Re: Marlin 1.1.0-RC7 for Mendel90 - 5 years ago
The top layer is sparse because I didn't re-calibrate E steps from PLA. Softer materials feed slower because they ride lower in the hob and see a smaller radius. You can never get to 100% fill with viscous materials like ABS because it won't flow under the rounded edge of the previous infill line when it is only constrained on one side. The infill spreads more to the unconstrained side and thenby nophead - Mendel90
Re: Marlin 1.1.0-RC7 for Mendel90 - 5 years ago
No I am using the NEMA14 direct drive extruder on my Huxley90 because the flexible filament I have is 1.75mm. It is like pushing string but with the right settings I can get 20mm/s. Here is a cap for my printed glasses case printed in 41 Flex polypropylene with 0.25mm layers. It prints very nicely.by nophead - Mendel90

Re: Marlin 1.1.0-RC7 for Mendel90 - 5 years ago
Just like Windows then. Endless new versions that make all your hardware go obsolete. I still have a machine with a Panalolu2 but no intension of ever updating Marlin to a version incompatible with ino as that is what I use to build it. What benefit does Marlin 1.1.0-RC7 have?by nophead - Mendel90

You could try asking them for the OpenScad source file as I expect they modified that rather than completely remodelling it.by nophead - Mendel90

Re: Copying Marlin profile from Melzi - possible? - 5 years ago
You need to select "Melzi W / ATmega 1284p 16 mhz". Melzi is not supported by Arduino, so you need to copy the Melzi board support package from my GitHub to the hardware folder. It probably only works with Arduino 1.0.x because Arduino keep making non backwards compatible changes which require all the BSPs to be updated each time. That is why I shipped a specific version of Arduino with the BSP aby nophead - Mendel90

You could try printing the first layer at a lower temperature or slightly higher or with a smaller W/T ratio to reduce adhesion.by nophead - Printing
Re: what does a bed heater cable failure look like? - 5 years ago
I have had a machine built from an early kit printing almost continually for the rest of the kit production and its ribbon cable is still working so the lifetime should be in excess of three years of printing. It is a fairly dangerous failure if it does go though, so perhaps it is advisable to inspect it say every six months. Maybe if you print lots of small things it concentrates the wear in theby nophead - Mendel90
Re: what does a bed heater cable failure look like? - 5 years ago
Hi Alex, That isn't the cable supplied with the kit. What happened to the original? I think the coloured rainbow wire is less flexible. Did you have the polypropylene strip installed on the inside of the bend?by nophead - Mendel90

Re: poly strip USA Can't find a source cheaply for sure - 6 years ago
For my first machine I cut them from polypropylene A4 binder covers. For the long X one I stapled two together. Anything with a living hinge will be made from PP. We bought large sheets intended for laser cutting. They are not expensive but postage is for just one sheet.by nophead - Mendel90
Re: Extruder Switched off MINTEMP triggered - 6 years ago
> MINTEMP message, printer stops and thermister voltage definitely drops to 0. That has be baffled. Dropping to zero implies a short but that should give MAXTEMP error. The only other way it could go to zero is if the pin was defined as an output and driven low. If you haven't changed the firmware recently then that can't be the case. Do the motors ever move?
