MKS Mini v1.2 powersupply? - 2 years ago
Hey Guys, I was given a old kossel mini that I'm trying to ressurect. It has a MKS mini v1. 2 board. I'm trying to figure out what the power requirements are, and Google is not being very helpful. It doesn't have/support a heated bed so I can't imagine it requires huge amounts of current. Does anyone know how many amps the power supply needs to be?by Lenny25 - Controllers

Re: Weird Marlin issue with LCD - 2 years ago
QuoteDust Ramps board have power issues, a lcd is all you can add (and that is pushing it) add in a bltouch and it needs to much current on 5v remove 5v/vcc jumper that powers the servo 5v pins and instead make your own 5v supply from 12v to plug into the 5v pin and connect the gnds Thanks very much! Sorry that I need to ask a few stupid questions: 1) I have 5v (16A) and 12v (18A) outputs onby Lenny25 - General
Weird Marlin issue with LCD - 2 years ago
Hey Guys Wondering if anyone can offer any thoughts as to what's causing this. So my system is Prusa i3 clone, with RAMPS 1.4 running Marlin.2.1x bugfix Changes made before the problem occurred: Installed a BLtouch sensor and edited the firmware to enable the sensor. So whats happening now is, that as long as the arduino board is connected to the PC via the USB everything works fine. If I dby Lenny25 - General

Thank you so much! Problem solved! - much appreciated @Dustby Lenny25 - Firmware - Marlin
Re: Cannot define heatbed sensor - 3 years ago
QuoteDust temp_sensor_heatbed is not valid. you cannot randomly change defines or the case of the defines, the code must be updated to match Sorry I was just typing it out in the post, in the config I havn't changed the case, just the value that denotes which thermistor I'm using. It works fine when defined as '0' but not as anything else, like '1'by Lenny25 - Firmware - Marlin

Cannot define heatbed sensor - 3 years ago
Hey peeps, I'm running Marlin 2 on Ramps 1.4 board, using the Arduino IDE. Everything is working perfectly and Marlin is compiling and flashing to the Arduino just fine, until I change the #define temp_sensor_heatbed 0 to #define temp_sensor_heatbed 1. I've tried changing the 0 value to all sorts of other values (the bed thermistor is a generic 100KOhms NTC), but no matter what I change it to,by Lenny25 - Firmware - Marlin
Re: Designs for i3 with Nema 23s? - 10 years ago
BTW If I was to change designs, to a XY Core or Delta. What would you guys recommend? What I liked about Prusa i3, and what I'd be looking for in another design is: I would like something that has a big community/support around the design. I've already purchased an Arduino, Ramps 1.4 kit with LCD, so I'd like to use that if possible. My preference is for the structure and majority of the partsby Lenny25 - Prusa i3 and variants
Re: Designs for i3 with Nema 23s? - 10 years ago
Ok, so I did some research on these steppers, and I actually think they might be perfect, because they almost spot on with the nema 17's required specs. So I'm assuming that they bi-polar because of the four leads (they got 6 pins but only 4 of them have leads connected to them) 1.8 step, rated at 1.4 A, 54 Ncm holding torque. These particular ones have a "low noise, low vibration laminatedby Lenny25 - Prusa i3 and variants
Re: Designs for i3 with Nema 23s? - 10 years ago
I saw that the cartesia uses nema23s. I was thinking of building a more heavy duty machine down the line, perhaps making a 3d printer/cnc mill combo. But i thought i should start with something simple for starters to learn 3d printing. That's why i was thinking i3. Perhaps i should set the nema23s aside until later...by Lenny25 - Prusa i3 and variants
Designs for i3 with Nema 23s? - 10 years ago
Hey Guys I've been planning on building a i3 for some time. I have access to a 3d printer, laser cutter and cnc mill. I've also been given 4 Nema 23's...and so I was thinking of using them instead of having to buy a whole punch of 17s. Has anyone ever seen an i3, with nema 23's, and if so do you know where i might be able to get models to print parts for it. Or do you think I'm going to need tby Lenny25 - Prusa i3 and variants
