Re: Looking for auto-leveling recommendations for my Metal Max

I would go for the FSR system. It's more easily portable to different control boards (Duet, Rambo, Smoothie, Etc.), and seems to not have the same level of heat soak/EMI issues causing it to not work warm. Considering that the Artemis has gone to FSR's, I would say that the accelerometer probe, whil...

Re: Hans makes a build thread for a Rostock Max V2

It sounds like you might be getting progressive damage to the thermistor wiring (because that would make the indicated and set temperature change while not messing with the actual temperature). How much of the wiring to the hotend have you had to change in attempting to fix the issue, and have you u...

Re: Ros tock V3 heated bed not getting hot enough

The only recalibration would be to re-tune the PID on the hotend, and that can often be skipped as well, as temperature regulation doesn't always have to be exact (yet I say that as a guy who hand tunes the PID on mine to swings of less that .1 degree to either side of set point, since I want the pr...

Re: Rostock max v2 with he280 hotend, Nozzle Not heating

To make sure it's the heater (which it's not too likely to be, since it worked in the first place), use a multimeter to check the voltage drop from one side of the fuse to the other. If it's near zero, it's the heater. Anything else, and the fuse needs replaced. If it is near zero, check the voltage...

Re: Rebuild on Rostock Max V2 questions

It is going to be firmware on the little board, as that converts from the I2C parameters to effectively a switch, but I was mostly referring to using it with a Rambo.

Re: Has anyone got Bltoch auto level, Repetier FW, RAMbo

Additionally, a BL touch or other offset probe is a major disadvantage when attempting to calibrate a delta. If there is a dip, or other non-linearity in the bed or motion, an offset sensor will move that over by whatever the offset is, meaning that instead of compensating for errors, you move them,...

Re: MetalMax Delta printer - belt catching on new linear rail - need advice please

Additionally, you want the belt to be flat at the height it is above the linear rail. If not, over a travel of say, 400mm, assuming that you have a smallish gap between the pulleys and the rail, there is ~.7 mm of difference in the length of required belt, if you had a lift of only 5mm. At say, 10mm...

Re: anybody in South FL??? rostock max V2 def error (thermistor heated bed or hot end)

The heated bed one may be vaguely correct, but the hotend one is definitely wrong. The RRC thermistor works, but I prefer PT100's personally, since I do some rather daft things (Hello, 450+ C printhead temperatures), and prefer the mechanical reliability. The RRC one is miles beyond an unpotted ther...

It can, but you will need to drill and thread a hole for a grub screw to hold it in place. Or you could try packing it in RTV (I wouldn't).

There are arm kits, as well as assembled and kit hotends and wiring harnesses.

The first step would be unplugging the thermistors, and using a multimeter to check them for resist...

There are three fuses, two of which are very small, and have no visual indicator. The one that's visible is the heated bed fuse. The others are just below the power entry point, and just inboard of it, under a capacitor. It's most likely you've killed one of them. they are relatively available. http...

Re: def has started to appear frequently destroying prints

So, the wiring most likely to have been damaged is the hotend wiring. I would do a resistance reading on each wire for the thermistor and heater cartridge, and see if the resistance changes much as you move the hotend around the build area. if you find one that does that, replace it. Once you've gon...

Re: Upgrade Option Questions

The stock power supply in the V3 should handle it fine. It has 29A, of which ~12 go to the heated bed, and ~3.5 goes to a standard 40W hotend, leaving you close enough to 13A for everything else. Now, at 2A for each stepper motor, which is rarely run because that much torque usually isn't needed, yo...
