KF 700 cutting a sheet of plywood in half
I'm wondering if there is a way on the KF 700 to cut a piece of plywood in half with a 31 rip capacity unit. I realize the overhead dust collector would be in the way. It looks like that would be cumbersome to remove. But if it were removed, is there anything preventing one from cutting a plywood sheet in half using the crosscut fence on the slider?
If that is the case, it occurs to me that this might be a good argument for the standard dust collection blade guard system, since it would be easier to remove the tubing, or better yet the hose could be suspened above the saw. I know others using this machine with me will want to know if we can handle cutting plywood in half.
I guess the issues are 1) is how hard is it to remove the overarm dust collection? 2) is there anything else preventing having 38" stock to the right of the blade for a crosscut??

Re: Felder BF 6 jointer table setup
On the question if one should use thread-lock or anti-seize on the set screws, I am still not sure. Do you find that you have to re-adjust the blades now and then on a machine of this type? The construction appears sturdy, so when it is set it looks like it should stay so, but reality is often surprising.? ? ?
As the blade heights were off up to 0.2 m.m. to one another I don't think there was another reasonable choice than re-adjusting the set screws. The set screws had had some strong thread lock on them, deeming from how tight they sat and residuals on the threads. I had to use heat to get them loose. Then, I saw that most inside threads were jammed above the top of the set screws heads. All set screws had to be loosened by screwing them inwards. Did they jam the threads at Felder, so nobody would tamper with the set screws? Beacuse I find it hard to believe that most threads were damaged this badly by accident. Fortunately it was possible to restore them with a tap and die.??
If we have to redo this process every now and then, thread-lock and oxide building up makes adjustments quiet a pain.?

This is the feature of having a separate motor for the scoring blade rather than having it be powered off the main motor.

the dust port was printed on a Markforged mark 2 and I did not use carbon fibre filament just the nylon with chopped carbon which is more than strong enough. Also if memory serves me it was $6500 not 10k will have to check the invoice or cc. I think the non carbon fibre filament is like 5k Regards, Mark

Well, everything is "relatively" strong ;-) It's all about compromise.? Some materials are "stronger" (vague term) than others, but there are multiple dimensions to "strong" -- stiffness, brittleness, creep, UV resistance, heat resistance, etc.? And different materials have slightly different printing characteristics -- some are easier to get quality prints with than others.?

The carbon fiber-reinforced dust fitting from the $10k printer is lovely.? You could also get a $100k CNC machine and make it out of titanium.? And you can also make it on a $200 printer, more than twice as fast and less than half the material cost as the MarkForged printer.?

They are most commonly referred to as SLA (StereoLithography) printers.? Unless you have specific fine detail requirements, like you're making jewelry castings, you don't want to start with an SLA. The resin is messy, parts need washing, etc.? ?And the working size to cost ratio is much different.? You can choose from a dozen FDM printers with ~10" cube envelope for ~$500, but you'd have to spend ~$2,000+ and have very few options to get that size in SLA.?? ?

PC is a difficult material to injection mold, very narrow temperature range and degrades under temperature very quickly, I think 3d printing requires a machine that has a heated bed and possibly heated print envelope. Like Brian said if the layers don’t fuse it all goes poo-poo.? Regards, Mark

Also, just because materials are available, doesn’t mean all printers will print with them.

They are most commonly referred to as SLA (StereoLithography) printers.? Unless you have specific fine detail requirements, like you're making jewelry castings, you don't want to start with an SLA. The resin is messy, parts need washing, etc.? ?And the working size to cost ratio is much different.? You can choose from a dozen FDM printers with ~10" cube envelope for ~$500, but you'd have to spend ~$2,000+ and have very few options to get that size in SLA.?? ?

I was searching strength of 3D printed items, since someone asked. PC was suggested as the stronger one for 3D printing. It was a general response so did not state how sophisticated a printer is required to print with PC. I understand your comment about cohesive interlayer adhesion, or lack there of.

If the layer on top doesn’t fuse (melt) solid with the layer below, no matter how strong the material is, the weak spot becomes the joint between layers.
Also, just because materials are available, doesn’t mean all printers will print with them.

Brian,
Are any of the materials you mentioned are poly carbonate?Google search said it has very good strength. If not, would an inexpensive printer handle PC?

You can get a decent 3D printer for $500 or so, but it’s going to take $3000-$5000 to get one capable of printing with carbon fiber enhanced materials (or a lot of modifications to a cheaper model). With most home type machines you can print PLA, ABS, PETG and a few other alphabet soup combo’s. PLA is the most common and easiest to print with, but it does have strength and durability issues. I printed a LED light mount for my CNC mill using it and it has held up ok, even under the spray of oil and water based coolants.?
I also printed up some replacement speaker grills on my van when I did the handicapped conversion… the side doors required all new panels to accommodate the automatic door openers. That had to be printed out of ABS due to the summertime heat (would have melted and warped the PLA). Using ABS requires that you enclose the printer and keep the heat enclosed or the print goes to hell.
I have not used the DLP (Digital Light Processing) models. The smoothness of the prints is much better than FDM (Fused Deposition Modeling) and I think they have units coming out that will print with fairly strong materials… at what cost, I don’t know.

I know this might be an off question and not trying to turn the thread but i love the idea of printing parts like this at home but have not gotten a 3D printer or CNC yet (I am looking at the Camaster CNC right now).? My wife was talking about being able to print small knobs and such - so considering one just got much easier :)
Are the materials made with these relatively strong and is there a large difference in the printers that build the part up layer by layer vs those that build with light in the epoxy?

Go to Matterhackers for a breakdown of available printing materials. I found PC listed, but it requires 280?C on the extruder and pretty high bed temps too, not sure my printer will get that high. A lot of nuances in 3D printing. One advantage, is there are
plenty of print farms that you can send your 3D deign to and they will print it for you, out of pretty much anything available... for a price.
