A Couple HS-1 Newb Questions

[ripper7777777]

I'm still new to CNC, I make parts for RC's and dove into CNC the first of last year and have learned on the way.

I started with the cheapest table I could find that fit my size requirements.

It's a MastersCNC table made from HDPE. It was cheap and came with lots of issues, but overall has served me well.


But now I'm looking at something that is a bit more accurate and dependable.

I mainly cut Delrin and every blue moon some 1/8" aluminum sheet. The delrin I get comes in 12x24 sheets so the dims of the HS-1 seem to be perfect since I rarely cut past 16"s.

I'm also looking at the KT1425, but I'm hesitant because of the unsupported x/y. I'm not trying to start a bash K2 thing just being honest about what I'm looking at.

My main questions about the HS-1 are:

What do I need to actually get cutting, I know I need a spindle, but do I need a mount, all the pics show it with a mount attached, so I thought I'd check first.

Does anyone know if the MDF will warp in weather changes. I use DS tape to mount a spoiler board and cut through the material every time, so I would just mount some stock plastic to the top of the MDF. But I live in houston and humidity changes a lot here.

What controllers and motors does the HS-1 come with?

How is the cleaning of this machine, Delrin is very messy, sends shavings all over the place, the machine I have now has no problem pushing the shavings aside. I'd prefer to clean up afterwards than have a vacuum running the entire time.


Ok currently a couple issues I have with my machine and I'm yet to work it out are:

My .125" holes always come out slightly larger or sometimes oval. I have tried many things and have gotten them really close. But I have determined that the table top was warping with weather (plywood) and the router mount was a bit loose on the bearings. So I'd like a router that I know can be accurate with tweaking and maintenance, not rebuilding and redesigning.


When I make multiple passes there is a line where each pass ends, sometimes very noticeable. I'm figuring this is normal to an extent and I need a finishing pass. The problem with my machine is the amount or thickness of the line is not consistent.

So again I'm hoping to find a machine that will deal with these issues better.


Any advice and or suggestions would be great.

I bought a WD-1 and just love it. I went with the wd-1 for the stability of ball-screws on both sides and the larger work area (21 x 30.)

Regarding your out-of-round holes... what speed are you running? I had to slow mine down for tight corners and holes. Run a test piece with several duplicate patterns at different speeds and see what works best for your machine.

Good luck,

I use MDF as a spoiler board, so far no problems. Depending on how much cutting I do I put a new one on every 6-8 months.

Last time I had a problem in my holes not coming out round it was due to a loose V-wheel on the Z axis.

I live in Cypress (near 529/Barkercypress, If you want to take a look at my HS1 you are welcome to drop by.

I also looked at the K2 routers, I picked the HS1 and have not regretted it.

Thanks for the info, but yea I have tried everything with my current machine and currently it cuts at a snail pace to keep any form of accuracy, which is why I'm looking for a replacement.



So I guess I'm still wondering do I need a mount for the Bosch Colt and what else do I need to get the cutter going, I'd like to make just one order.


Also what motors and controllers does it come with?



George do you have the aluminum table or the MDF?

[georgemyers]

Gecko's and the steppers are KL23H276-284B's. and looks like the router mounts are not included, not sure tho. I have had my HS1 for around 2 years so it may be different than one you get.

I have the aluminum but use MDF on top of it.

If you don't want to make your own dust boot be sure to pick one up from Ron, well worth the effort or price.

[ripper7777777]

Well the order is placed, now I just have to wait.
