Re: New Hotend possible - 11 years ago

Quotecristian Quoteregpye Differences with the new model. Hi Reg, in your opinion, what is the difference in terms of printing? Besides of course the fact that the hotend is lighter (which is good for the smartrap, given its design). The "cold zone" seems shorter, maybe also the "melt zone"? What would this imply when printing? The hot end of the hotend is actually the same as the MK1. Only re

New Hotend possible - 11 years ago

I have been working on a new design of hotend and if there is enough interest I will start a production run. This hotend is based on my previous design that has been very successful. Expressions of interest please so I can determine if I should go ahead with a small production run. Differences with the new model. It will be much shorter in total length. It will be fitted with a 16mm diameter m

Quotemikefiatx19 HI Guys, Thanks for the huge amount of support, I will try to reply to everyone now. RTurnock. . Then I will look into tuning the pots to get the motors running smoothly. When you adjust your pots you will need a multimeter that can read in the low voltage range setting. I have found the best and easiest way to do this is to get a second set of multimeter probes and modify

Re: Bed Auto Leveling.. check this out - 11 years ago

QuoteAbuMaia QuoteDraobSome printers who have a metal bed use a magnetic sensor directly on the carriage and get the same results with +/- .05 precision everytime. Would a Hall effect sensor be able to detect a magnetic field generated by the current in the heatbed (if there is one)? My guess is No, because the magnetic field would not be exactly the same in different places on the bed. These d

It is working and I can print (although I want to design a hall probe for the i3 rework for more precision/repeatability) I would be interested in working with a hall effect sensor too,but so far I can't work out how to implement it. My i3s are all using servos and micro switches, and sometimes I have to re-calibrate because the settings have chan

I did a bit more on the machine today. No photos, but I got most of the wiring done. A few more afternoons and I should be able to program the board and then test. I have to try and fit all my jobs in so that I can complete them all, so it is taking a bit longer than I expected for this one.

Re: New to 3d printing with smartrap need some help - 11 years ago

QuoteBackEMF i'm experimenting with this but when the arm is half way then it already struggles a bit and when the arm is fully extended then the slide tends to block / get stuck However when I just press manually then it seems to be working just right. So when the arm is extended the x bends enough to make an angle that gives enough force to get the slide stuck on the friction. This resulted

Quotenapalmvictory Not so much a design as it is a concept. Stabilizing the Z axis with cables. Might add a couple inches to the Z height on a number of printers if it can be properly implemented. Yes, they use that idea on bridges and it sure holds a lot of weight too.

Quotenapalmvictory Hey Reg. The vertical support idea is good. I've had a little success with 1/16" wire rope as opposed to structural support. Could be applicable to your predicament. That is an interesting design in your photo.

Quoteduranza I like where this is going. Interchangeable hot-ends already bolted to the slide. Now if we can make the wires with some sort of plug in/ disconnect we would just move the switch, and slide the new one in. Here is a captive nut version so that no tap is required for the M3 bolts. It is just the slide part, you will need to download the previous design and then use this with it. cap
