Quotecristian Too late for me! I printed the smartrap X end for the MK2 yesterday evening. And tomorrow I will start my tests, finally. I should have the results in a week or two. You are really on the ball Cristian. Looking forward to your tests and see if there is any difference between the MK1 and MK2 with what you are doing.by regpye - Smart_Rap
A number of people have asked me about the grooved nut that goes on the Genie MK2 hotend. It can also be used on the Genie MK1 hotend if needed and is also reversible so that it has different lengths because the groove is not in the middle. Here is a drawing of the grooved nut and also I have made an STL file for download if you want to print one out for fitting or using while designing a mountby regpye - Smart_Rap
Quotefabrice974 with this, everything should be clear After looking at the edrawing, I can see that it should work fine. Very nice design. You need a good hotend to go with that.by regpye - Smart_Rap
Quotefabrice974 now full gt2 version result soon I like it. The design looks very familiar ha..ha.. What have you added to the Z axis, the drawing is not clear on that area?by regpye - Smart_Rap
QuoteBackEMF Hi Loidor, I'm using Regs Genie hotend (and i'm very pleased with it) I'm cooling it with a 12V fan constant on 5V. This cools enough and doesn't make any noise. Mine has Kapton wrap, it can probably be build without Kapton but for me it's ok with the kapton Shipping from Australia to the Netherlands was $18 and it took a few weeks. It can be used without the Kapton tape. The heaby regpye - Smart_Rap

Quotecristian QuoteBackEMF why not use GT2 belt? The only Smartrap design I saw so far with belts on the Z axis is one of Reg's designs, so he can better tell the pros and cons of using it. The reasons why I did not use gt2 belts are that I should have changed considerably the design of my printer, in particular I should have used some geared system to increase the step resolution along Z; I shby regpye - Smart_Rap

QuoteBackEMF I had a bad experience with LM8UU, when the rods are not 100% parallel then the pressure on the bearings causes damage, bushings make a lot of sense to me. 600hours seems a good lifetime already. Less damage, less noise, smooth operation. Well, let me place an order! I like to give it a try. Wait a few days and I will have an order come in of a 1000 commercially made ones.

QuoteBackEMF It depends on how you approach it, i kinda like the idea of a printer that is going to be upgraded after a year or 2. The speed of technology is fast enough to have a better machine when you upgrade to a new one, and recycle electronics and rods of the old one. in my opinion thats just as expensive as buying an expensive machine that needs to work 10 years to make itself pay backby regpye - Smart_Rap
QuoteBackEMF 76 percent 3D printer owners report high daily & weekly usage, finds new CEA study The header seems to be a bit hyped up, since I can't actually find it in the report. Or is this just a media trick of make-believe? An interesting read. From my personal experience of other users around my area, they are using their machines almost daily too, some staying up most of the nightby regpye - Smart_Rap
Coming up to 500 hours printing now and still going great. Have lots of parts printed, several more machines to put together now and a lot of Christmas presents printed. I can't see any wear in the bushes so far, so I will continue printing some more and see how long it can go before failure.by regpye - Smart_Rap
Quoteloidor Quoteregpye Hi ioidor, where is around here? you can't be more isolated than me in rural South Australia. Rural South Australia is like the suburbs compared to foresty Sweden, I'll tell you. ;-) Or, well, not totally, but since one metre of 6 mm axis rod is worth about 40 Swedish crowns (£4 or something) at the most (might even get it for half that price once I find a bloody sellerby regpye - Smart_Rap
Quoteloidor Quoteknife-edge Why not build a Smartrap from the start? You can buy the plastic parts on eBay or I'm sure someone here on the forums to would be willing to print you a set. Well, first of all I got the wood, and secondly I will remix it a little to get rid of the 6mm rods (these are totally impossible to find around here, and I already have 8mm),and lastly it seems a bit... Too easyby regpye - Smart_Rap
Quoteloidor Also, if I'm not mistaken I should be able to turn them down to getting about 1A, and they should still have a torque of about 0.5 Nm. Right, so now it's just that damn waiting for them parts to arrive... Blimey, why is China so far away? In Australia which is close to China really, it still takes about 5 weeks for the free postage to arrive. If you want it quick, 3-4 days, you haby regpye - Smart_Rap
Quotecristian QuoteBackEMF Another way to reduce wobble might be one of these: the flexible connection might do the trick. If ithe prices aren't too extreme. And what about printing a flexible coupling? I tried to print a flexible coupling and I failed: it is difficult for me to conceive a coupling that preserves rotation and z shift, while being tolerant on x and y shifts...

I have a friend that does not have an Internet connection, so I am searching for him about his problem. Although I have a similar machine that is using RAMPS, I have not come across this particular condition. Everything seems to be working as it should, prints very nicely and then all of a sudden the Y axis will make a noise and skip some steps. It sounded like the belt slipped, but after checkinby regpye - RAMPS Electronics
I am trying to work out what time is used for printing over a month by most users. The reason is to see if I can base this amount on what life there would be in a printer (on average) As new models are coming out all the time and many changes take place in a short space of time, I would think that the average printer life would actually be quiet short. I know some would buy or build a printer andby regpye - Smart_Rap
Quotemandrav Quoteregpye A number of people have asked me about a mount for the Genie hotend and as there are so many different machines out there, I decided to make a generic type that can be bolted with just two bolts onto any flat surface. This means that a very simple design for mounting the mount on can be made and suit many different machines. The Genie mount has provision for a 30mm fan foby regpye - Smart_Rap
I experimented with some sublimation ink and just wiped it on the side of some filament before printing. It certainly colors the filament and it is all the way through to, but I didn't have any way to control it. I wanted to see if the sublimation ink would color the filament and that was very successfulby regpye - Developers
Quotecristian Quoteregpye Smooth Z rods thickest you can use. Threaded Z rod the thinnest you can use. No retaining bearing at the top end so the threaded rod can move as needed and not force any unwanted movement to the axis. Use stainless steel thread for better formed thread. A good bearing system or use bushes that are free and give a good sliding action. Thanks Reg. Have you ever managed toby regpye - Smart_Rap
Quotecristian QuoteBackEMF For now i managed to compensate the coupler wobble by turning the rod so that the two wobbles cancel eachother out a bit (it still wobbles a bit) I went to 2 hardware stores today only to find rods that are uncapable of rolling on a flat surface. :-) Not bend a lot, but bend enough to leave them on the shelf and look further.. At the top, the rod wobbles not more thanby regpye - Smart_Rap
Hi Cristian, Nice results from your machine, regardless of the Z wobble. Out of interest sake, which slicing program are you using? To me it looks like you may be using Cura?? If so, can you try using Slic3r and see if that changes anything in the results?by regpye - Smart_Rap
Quotemikefiatx19 Hi Reg, The hotend arrived and I am ready to fit the unit. What X-end do you recommend to fit the Genie to the Smartrap 4.9 (6mm rods)? Thanks Mike I have made a generic one that can be used if you can get a flat plate printed that fits the 6mm rods. It is only held on with two mounting bolts that hold the mount together and can also be used for fixing to a flat printed plate.by regpye - Smart_Rap
Quotecristian Yep, much more visible now. I am very curious to know the new assembly procedure... I will work on that tonight and post it. Too much to do today, but it will be worth the wait, believe me.by regpye - Smart_Rap
I have added a better link within the main menu system now Cristian, still not updated the page though, too much work on at present, but it will be done soon. The later method of assembly is so much easier, and also works the same for MK1 and MK2 hotend models, so I need to get this done ASAP.by regpye - Smart_Rap
Quoteknife-edge Yup I printed a new bearing plate and bearings lined up so terribly. It took two hours worth of filing to fix it. I made the bushes so that the two are joined together and that eliminated the alignment problem. The ID opened to 8.3mm and when the rods are adjusted the small gap is taken up so there is no play what so ever. It also stops any binding. There is no need to haveby regpye - Smart_Rap
Quotenophead Yes they are lower friction, quieter and won't wear the rods, but will they stay tight for any length of time? My experience with Igus plastic bearings is they were great for a few builds but after that the carriage started racking. My test machine has now been running for 115 hours non stop and doesn't seem to have any issues yet. Very quiet, smooth running, prints are very good. Wby regpye - Smart_Rap
