Re: Finally upgraded z-axis on p3steel, but I am having stepping issues now. Seeking help. - 7 years ago
Thank you Dust and Roberts Cliff. I'm sure you must be right about the lead screws being "4 start". This was my first ever lead screw purchase and I have to be honest, I didn't know about different 'start' values. The product listing I bought didn't mention start count anywhere and the calculators don't mention it, although they do mention height per revolution. However, wouldn't changing the sby ML3D - General
Finally upgraded z-axis on p3steel, but I am having stepping issues now. Seeking help. - 7 years ago
Hello. So, I have a p3steel that I cobbled together a number of years ago. I have finally upgraded the z axis by installing 8mm lead screws in place of the M4 threaded rods I am running RAMPS with DRV8825 drivers. PSU is 12 volt. The motors are Kysan Nema 17 with 1.8 degree and 1.5A per phase. Both motors are running off of the one Z stepper driver and they are connected directly to the Rampby ML3D - General

Re: Temporary Support Structures - 11 years ago
Meshmixer also has a pretty interesting support structure feature. Seems to work ok, but if you make the support diameters too thin, they'll likely break during printing. Takes some experimenting.by ML3D - General

Re: P3steel y axis belt idler problem - 11 years ago
Mine pulls off to the side as well. I do plan on doing something about it eventually, but so far, it hasn't been a problem. Good luck with your design. Let us know how it works...by ML3D - Reprappers

Re: Aluminum Heat Bed High Resistance... is this normal? - 11 years ago
cdru, wow, thanks, very enlightening information. I'm a rookie when it comes to electronic calculations, such as Ohm's Law, but I'm slowly learning more about micro-electronics in general. I have PCB type heatbed on order, and I already have the glass, so I'm going to see how that goes next. I may try another aluminum bed in the future, but only if the dealer can assure me of a proper resistancby ML3D - General
Re: Aluminum Heat Bed High Resistance... is this normal? - 11 years ago
I metered the Amperage from the Ramps board to the heatbed. At approx 14 volts, it was only drawing 6.5 amps max. It should be pulling 10 Amps, correct? Although with the voltage higher, that would affect the Amps, I think. I imagine this could be the high resistance, ramps board ( mosfet? ) limiting amps, or perhaps the power supply itself.by ML3D - General
Re: Aluminum Heat Bed High Resistance... is this normal? - 11 years ago
Yup, wired correctly. cdru, thanks for confirming what I thought may be the case. I really like the aluminum, but honestly, now I'm worried that if I fork out for another, it will have the same issue.by ML3D - General
Re: Aluminum Heat Bed High Resistance... is this normal? - 11 years ago
Hi Tim, thanks for the reply. The problem is the common one of limited temperature and speed of heat up. Details are: 200mm x 200mm MK3 / MK2b Aluminum Heatbed, wired to Ramps 1.4 with 14awg wire to board and to power supply. Power Supply is the standard 12v 30A switching type, commonly called an LED power supply. Ramps has a heatsink on the Mosfet. It's being powered with 14.7 volts. The D1 dby ML3D - General
Aluminum Heat Bed High Resistance... is this normal? - 11 years ago
I have a 200mm x 200mm MK3 / MK2b Aluminum Heatbed and resistance measures a high 1.9-2ohms ( this is after subtracting the resistance in my cheapo meter ) Is this normal for the aluminum beds or is it possible mine is defective?by ML3D - General
Random Y-Offset during print & other oddities - 11 years ago
Long time lurker, first time posting. Been following reprap for many years. Recently took the plunge and built a P3Steel Prusa from parts I sourced from a multitude of vendors. My electronics consist of a Ramps 1.4 setup w/ drv8825 drivers. Motors are the standard Kysan. Power supply is the standard 12v 30A 360W DC switching type ( not an ATX unit ) I have heatinks on the drivers and I have a faby ML3D - Printing
