Hi all. Spent this weekend upgrading my RAMPS Huxley to the latest (1.0.2) version of Marlin. After going through setting it up and then having a lot of fun(!) re-doing the menu I have an odd issue: The print won't start. My initial G-Code heats the bed to temp - and waits for it to get there, before homing and heating Nozzle etc. Printing ABS, bed set to 105C - the LCD states that it gets theby rainingheavy - Firmware - mainstream and related support
Quotedc42 Hi Michael, On my Ormerod (with Duet electronics and firmware), cool down when a tool is deselected is controlled by setting the standby temperature in a G10 command. So slic3r is not involved in it. I've not looked at what commands slic3r generates if you ask it to control standby temperatures. However, I did notice that slic3r generates M109 and M190 commands with an additional T paby rainingheavy - Huxley
Quotedc42 Your dual head mod for the Huxley looks very similar to the way I converted my Ormerod to dual head. I've documented the process at . In the process, I discovered a few things: 1. The standby temperature of the non-printing nozzle is very important, to minimise its effect when it passes over the print. For PLA, I use 185C for the printing nozzle (increased to 195C for the first layer),by rainingheavy - Huxley
QuoteSean Eldridge Hi everyone. I need to replace my circuit board on my Huxley 3D printer and was wondering if the circuit board for sale here would work with my printer: If it doesn't work with the printer I was hoping someone would know where I might be able to purchase one for relatively cheap. Thanks! Hi, The melzi is the stock controller for Huxleys (and Mendels) - from reprappro at lby rainingheavy - Huxley
Quote3Dmaker4U Whenever I have to print with support, I use the 0.9.1b version The versions after generated an "indestructible" support, while the latest introduced pillars that cannot actually support too much. I know the model, but is not very efficient. The issue is that small fans, including 40 mm ones, cannot sustain the air flow if it is obstructed. I currently experiment a bi-lateral arby rainingheavy - Huxley
Quote3Dmaker4U Great job, congrats! I also had a plan to do that, but I managed to get better support management and, since dual color didn't sound too appealing, I just dropped it. One question about the "local cooling fan". I cannot see from the picture if you use a "duct" to direct the air or just simply hanged it at an angle, but my question is about it's efficiency. I mean, is the air flow iby rainingheavy - Huxley
Hi all. Part 2. I pinched the parts for the extruder drive from a kit I'd printed earlier, and after ordering the same NEMA17 motor - with the 6 pin JST PH connector; no flying leads - from china (AliExpress) I found out that to install the drive on the opposite side to the original I'd need to extend the mounting bar by 20mm. This was another model-from-scratch job. While I was at it, I alsoby rainingheavy - Huxley
Hi all. I thought I'd document my little project here, in the hopes that it might inspire someone. Or just so I can look back and work out how to put it back together... I bought a Huxley a few months ago, and once it was properly set up, it prints beautifully. However, one of the shortfalls has been its lack of support material. Same material support (Slic3r generated) is pretty terrible, andby rainingheavy - Huxley
Quote3Dmaker4U And in pins.h the assigned number is the number of the D-igital (or A-nalog) pin. For example, #define HEATER_BED_PIN 16 assigns pin D16. You can use the I2C pins SDA/SCL, which correspond to D20/D21, but you have to make sure I2C function is not activated by default (which I assume is not, but you should better check) in Marlin. Finally got 'round to sorting this, and would yby rainingheavy - Huxley
Thank you, I should be able to work it out now. Cheers, Michael.by rainingheavy - Huxley
Hi, Thanks, that helps a lot. I'll be sure to let you know when it works. On another note, rather than starting a new thread, what thermistor settings should I use; stock huxley thermistors. I found somewhere that mentioned the bed thermistor code, and number 8 matched, but the temp reading was wrong. (9deg instead of 26ish) Using number 1 I have them reading a number that works, but I feel likby rainingheavy - Huxley
Hi, This is exactly what I was after, however, I also use the LCD (it's the sainsmart ramps kit with lcd etc. - but no microstepping jumpers! > ) I have the I2C pins free (4 next to endstops), the unused max endstops, or Aux1 and Aux2 which need header pins... How do you know which pin is which? I assume there is a pinout diagram, but I've struggled to find it... Cheers, Michael.by rainingheavy - Huxley
Hi all. Upgrading my Huxley from Melzi to Ramps 1.4, in order to add a second extruder. Slowly getting my head around the Arduino software; the printer seems to be working, it moves and the hotend heats etc. My current difficulty is connecting the Heatbed. Ideally, I want to use the mosfet so I can run it from the stock 19v PSU. I've tried connecting the mosfet control wire to the heatbed conneby rainingheavy - Huxley
