Topic: Simple Arithmetic (or whether to buy and/or when to dump your DaVinci)
I thought it would be valuable to do the simple arithmetic to figure out the smartest advice when it comes to purchasing a 3d printer.
Here are the facts:
DaVinci 1.0A: (You can't buy a new 1.0 anymore)
$500.00 (currently on sale at $400.00 on amazon)
Cost of a XYZ filament spool:
$28.00 or .04666 cents a gram
Cost of 1kg of Printer Outlet natural filament:
$21.50 or .0215 cents a gram
Note re filaments: Yes other filaments are more expensive, but I've been using Printer Outlet filament without problems and while your favorite filament may cost more, the actual cost of XYZ filament is a actually a lot higher than $28.00 a cartridge due to all the problems with their filament system that result in wasted prints and unused filament. etc. etc.
So the XYZ filament charge is .025166... cents per gram extra.
Which means that each XYZ spool you buy is costing you around $25.00 more than another brand of filament.
Question 1: Should I buy a resetter?
Just about two spools of 1kg spools will pay for the cheapest practical resetter. (probably best to avoid XYZap2 and XYZzap2+ as these earlier models probably won't be able to keep up with all the curve balls that XYZ is sending). The XYZPRO @ $70.00 is probably the best bet. But the basic problem with a resetter is that you'll always be playing a game of catchup... you may be stuck with a firmware or XYZware version that could desperately could use an upgrade (particularly if XYZ changes to actually trying to improve the software, rather than devoting all their efforts to just locking down their system and trying to get rid of resetter users).
Question 2: Should I change to Repetier firmware?
However, $70.00 is still $70.00 and you don't need a resetter if you take your machine erase the firmware and load it with Repetier firmware. It's free and as most of the bugs have been worked out. However, as I understand it, going to Repetier on a 1.0A is a one-way street and you cannot restore it to XYZ firmware. On the other hand, XYZ firmware is becoming more and more useless as time goes by, so why bother? And if you're concerned about warranty service, think again. XYZ support and warranty service is abysmal. Encounter any problem and you're asking for your machine to be out of service for at least a month as they require you send them anything (at your expense) before they send you anything to replace it. For anything small like an extruder that won't cost you a lot, but if they want the whole machine that's at least $80 or $90 shipping. Plus warranty repair and support generally is primarily about making it difficult for you to get your repair done. They'll snowball you with silly requests and demands for documentation that are just inappropriate. So yes, as soon as you've gone through your free included cartridge (use it to print off a spool holder
) and you're reasonably satisfied that the machine is in good working order then flash to Repetier and don't look back.
Question 3: Should I buy another machine?
I think the answer to that is NO. At $500 (or $400 when its on sale at amazon or newegg) it's hard to contemplate shelling out at least $500 more for the next most affordable pre assembled printer (a solidoodle @ $1000). While that difference only represents 20 XYZ cartridges... if you flashed to Repetier, XYZ cartridges are no longer an issue anyway.
Buying a $500 dollar DaVinci lets you play around a bit, (sure go ahead and buy a 2nd cartridge if you must), try printing off some things you've download from Thingiverse, maybe fire up a cad program and see how you feel about the whole design/print process.
But is a machine that's a thousand dollars, or two thousand dollars or more that much better a machine? I've heard various claims in that regard, and I would say if you're looking for a machine to provide you with superior dimensional tolerances then even a $2,000 machine isn't going to meet your requirements.
The fact is you can't even buy a non-enclosed reprap kit for the money that a daVinci costs. If you're a first time purchaser and a daVinci flashed to Repetier turns out not to be the machine you need, then you can sell it on ebay for at least a couple of hundred dollars and your two or three hundred dollar loss will equip you to make a more savvy decision in the future.
If nothing else, the low cost of the daVinci is driving other printer prices down. Far better to have lost $300 on a daVinci than trying to peddle a used Makerbot for a $600 or $700 loss.
Question 4: So buy a daVinci, is that it?
I'm intrigued by carl_m1968's intention to swap in a totally different controller, basically just using the daVinci as an assembled kit and truly dispensing with XYZ. It will be interesting to see a new controller provides a more pleasurable experience that my current one with XYZ which is leaving an incredibly bad taste in my mouth. If think's work out for carl_m1968 then i'll be the very next one in line to toss out my XYZ motherboard. The board carl_m1968 is looking at is only $100 bucks.
Once you've tossed out the motherboard you're just down to stepper motors and bearing and rods anyway. Incremental improvements at that point might be kind of fun and cost effective. The point is, once you've cut the strings to XYZ I'm predicting you'll have a sense of freedom that'll allow you to make the modification you'd like to make without the nagging feeling you're ruining your machine by making it non-xyz.
Depending on how easily one can install a different motherboard in the machine, you may actually be able to restore it to stock more easily than the Repetier route. Just remove your 3rd party motherboard, reinstall the daVinci motherboard and you'd be good to go. So perhaps tossing out the motherboard will prove to be the recommended first course of action.
And, at this point, I just like the idea of expressing my disapproval for XYZ's ink-jet printer business model (i.e. sell the machines at or below cost and then make your money on the ink) by buying one of their below cost machines and then just slapping in a new controller.
