Re: Update

I really don't see the point of this post.

I don't think there is any such thing as a "flat bed" and that is one reason why mesh bed levelling was introduced to this printer.

As for your printer being out of date, well, so is my Mk1. But what's the problem with that? My Mk1 is still printing as well as the day it arrived and at any time, I can simply order an upgrade.

I suppose you are one of those people who believe that when you buy something, no further development should then be carried out?

Re: Update

To be fair pretty much most of the "upgrades" you can print yourself.
The only benefit from the "S" model shipped is better rods and bearings.
I actually binned my bearings straight out of the kit and built it with Drylin bearings. In real terms of what you're missing out on isn't a great big deal. If I thought that upgraded rods would bring THAT much to the party I would have purchased them myself as an upgrade anyway.

I've upgraded the fan, the bearings, the fan shroud, the vibration feet, added a Logitech camera, changed the PEI sheet for Printbite, printed better braces for the bearings, replaced the nozzle with a hardened steel one and probably a few other things I have forgotten.

It's no big deal. I get you feel a bit sore over it but as mentioned above, you should still have a capable printer that will print way better than 99% of the other printers in this price class.

Re: Update

sorry, but if you compare it to the car industry: the mk2s is nothing more than a slightly small facelift. no real "improvement" with new functionality... just altered some parts to gain a little bit more reliability and face some common problems.

@michael.p12: you should be common that there will always be some updates and that the release cycles are going to be shorter and shorter.
otherwise you would have to wait.... and wait.... and wait for the final release of a product. which in fact means that you have to wait forever, will never buy any item and miss the whole fun of innovation.

Well, I think that old good glass surface heatbeds used to be flat enough 🙂 The problem is with manufacturing process of new PCB heatbeds producing everything else but flat surface.
Unfortunately, MBL was originally designed for other purpose than "fix my crippled heatbed" problem. Yes, MBL produces almost perfect first layers (most of the time), but it should also be said that any such heatbed imperfection is silently transposed to top solid layer. As far as I know, MBL only recalculates Z coordinates depending on current XY position and does it in all print process from bottom to very top layers.
Sorry for offtopic.

Re: Update

I really don't see the problem. You got exactly what you paid and agreed to wait 7 weeks for. The bed issue has been blown out of proportion by some and if it is that much out of spec Prusa has replaced them. Is mine completely flat, on one yes but no on my second printer but I have found ways to make it work reliably.

Would I buy another? ABSOLUTELY!

You don't remember the warped glass build plates of the Mk1 then!

You're right. I usually use 3mm mirror glass, which is almost perfect flat. I don't know anything about MK1 glass plates, I've been using other printer type/model.

Yeah, I came from a near-perfect aluminium build plate of a Chinese clone to the Mk1, with tempered glass that was nothing like flat. Fortunately, the heated bed was also not flat, so if you put the high side of the glass downwards, it sort-of compensated.

Problem with tempered glass is the temperature extremes used to make it; very unusual to get a flat piece.

Re: Update

Pjr . The point is it's out of date after two weeks.and Sharron you have proven my point.you bought new bearings because the ones with the printer are inferior.

Re: Update

Pjr . The point is it's out of date

Yeah, and so are my TV, washing machine, dishwasher, oven, hob, camera, smart phone, computer, .....

And no, I didn't make a fuss about any of those things. As mentioned before, you chose when to purchase. You got it wrong. Your fault.

Peter

Re: Update

This is just pointless crying about nothing. Have you even tried the printer? I got mine not long ago and didnt get the s model either. I couldnt care less. My printer is f**king awesome and prints perfect prints like a champ. If your bed is warped. Contact prusa and talk to them.

Re: Update

PJ.don't think all of you stuff was updated in two weeks.and as for contacting perusal.sent them the same text i put on here .No reply about the bed.just this from Max Kaulfuss .the update is designed especially for customer who have the MK2. We made it as cheap as possible so everybody can have the MK2S :-)). With a little smile.which means got you.is this why they had troubles with PayPal so you cannot get a refund.

Re: Update

Michael

Sounds to me as though you really don't want an excellent printer at all.

Why not sent it back, get a refund and buy a Chinese clone with the money. That way you will get a brand new 3D printer which will be out of date in a couple of weeks or so.

Unfortunately, you really have to accept the very simple fact, that there is never a "right time" to buy a product which is being improved upon on an almost daily basis.

If you can't accept that, then you should stay away.

As for the warped bed, I would refer you to my earlier post and that of Robin. If you ask a question of support in a pleasant manner and provide appropriate pictures, I am totally confident that you will get a sensible reply with a working solution.

Peter.

Re: Update

I understand completely and because of this I am willing to take your outdated printer off your hands. As it is out of date I am only willing to pay half the retail cost though.

Re: Update

I didn't prove a point by saying I updated to Drylin bearings.
This was my choice. The Supplied ones would have been more than adequate.
Making this change was for my own satisfaction.

We do these things because we CAN, not because we NEED to.

Credit to Prusa for making a mid cycle revision of their kit.
I could create a wish list of other modifications I would like if I were to buy another, but that's not to say it's expected.
