Afternoon all.
Need a little help with something, and couldn’t think of a better place to ask then here among friends.
You guys have looked for a dust solution for a while from our group. We have been working on this and have a nice solution. The solution is not complete as of yet. We would like you guys to have the first chance at purchase, use and comment and have priced the dust boot just for that. This price and link will only be posted here and just for you guys. It wont be up long. Please contact us at contact@smw3d.com if there are any questions after.
Hmm, that’s not an SMW3D link! Here comes the next surprise. We have been working on a site in the background for about a year. You guys will be the first to visit the site outside of our team. Venture around, have a walk-through, see what our new digs looks like. The site is not completely done (A LOT OF WORK) but getting close. After the dust boots are gone the link will go back to maintenance mode. We will treat this as a type of acid test :).
Oh – almost forgot, that is not a 400w in the image either… There is a 600W spindle and spindle clamps that we have been putting through the coals. It is a monster and spindle speed control via the M1 is amazing!! We don’t know the life of the unit yet, we are only at ~100 hours of testing. Want to join the fun? These are also beta priced for anyone wanting to step up the power.
Mr @Rod_Shampine you are the first official customer of Hobby-Fab sir! Thank you! Seeing a an order on a system that has been in the process of building for a year is pretty huge. Thank you again.
Looking good. I may be interested in the boot after I test my current design and it fails… How long do we have to get this deal? —
More interesting to me is the 600w spindle. As I read it, it comes with a speed controller for $147??
1.) Is the PWM input compatible with the tinyG digital PWM out? …
The picture seems to show analog and PWM control.
2.) Has anyone tested the linearity of that speed controller with digital PWM?
3.) I assume this is a brushed motor?
4.) Looks like I will need a new spindle clamp [57mm] ($29), can I assume this will fit on my machine without mods?
4.) Any specs on the motor performance such as speeds, torque curves, inductance etc?
5.) Schematics on the motor controller? @Brandon_Satterfield you know I had to ask…
I also emailed these questions to the adr provided above.
Morning Don.
Happy to lay them out here.
Not sure on time on dust boot. Highly possible to be gone today, which means this post will be gone… hope you get this before it’s deleted.
Back on track.
Yes PSU and speed control.
I have not tested on the TinyG. I still believe the output is non-linear. By-gones.
The output from the M1 PWM did not fair well, there was a float. When I used the 0-10v, then did the piece-wise linear fit the RPM control was the best I’ve ever seen. No float and within 50 RPM across 87 to 13700 RPM on the first try.
Brushed motor, will be curious to see the life. There is an extra set of brushes in the box from my manufacturer. That normally tells me something. Time…
Correct the clamps fit on the 20x60 with the same hardware as the 52mm
We received a torque curve but something was wrong with the graph never chased it further. How much do you trust a motor manufacturers spec sheets? In industrial motion control, everyone lies. Dunno, I like product in hand. I can test and know the truth. I’ve not been able to reach 2 Amps yet. There is a digital amp read out inside the box. I skipped a belt tooth before I reach 2 amps. I was also doing 4mm DoC at 1000mm/m and had slowed the RPM to 8k. Belt skipped on Y.
Schematics, yep. Do know why you ask. If it was made in the US and commercial not likely to have schematics, if it’s made in China it is copied from somewhere else. No Don, not at 147.00 there is no schematic bud. Not sure what I would do with one if there was. I’m not tearing into these things. Course I’m not sparky either.
@SMW3D I am willing to invest in testing and getting it interfaced properly to the tinyG digital PWM for us all [I interpreted that from above it is not working].
To properly interface to the tinyG I may need to create a schematic like I did for the RioRand and I will donate that as well… I am a sparkie :).
But I don’t want to buy it and then find it will not work? As you know I am building a spindle driver and already have designed a proper interface from the tinyG. I concluded that the RioRand driver is not precise enough to get the programmatic speed control I want without tables and pot fiddling.
If this spindle driver is better I may drop my current effort and get back to using my OX :).
What would you suggest is the best way for me to be helpful and try out this new setup?
Im nw a customer, ordered the boot. What you don’t mention or maybe I skipped it is that your boot is static (stays in place vertically) while the z-axis moves. This is exactly what I’ve been looking for on my OX. There are a number of designs that move with the z-axis since there are plenty of places to mount. The challenge with static boots is where do you mount this thing with the limited size of plate. I have a 500W spindle that I can’t wait to test this with.
Shipping:
I found the shipping costs to be high for shipping to Canada.
@SMW3D I ordered a M5x65 bolt with my boot order. Now I’m thinking about it a little and I don’t think the 65mm bolt will be long enough to also mount the boot. What are your recommendations to mounting the boot.
@Rob_Mitchell Thank you Rob, these are things we need to look at. Shipping through SMW3D took almost a year to finally get correct. We will look into true shipping cost and provide a refund for the extra. @donkjr awesome brother. give the team about a week to hook it up to a TinyG. Last run made with an O-scope we found the output frequency signal was not linear to the inputted S.
We did try it on the M1 PWM and noticed a fluctuation, does not really make sense, but more investigation is required. After that we will let you know if we can work together to get this dialed in.
@Rob_Mitchell let me get back to the office and look at the BOM. Can you provide a length from back face where the head on the bolt stops to the back of the nut? Trying to recall, seems about 7mm worth of thread is required in the arm bracket.
@Brandon_Satterfield Ordering now. I realize this website is still new (congrats BTW!) so I hope this is received as constructive feedback and not whiny. Looks like a typo:
@SirGeekALot thank you brother. Actually just used you to see if the Abandon cart notices worked… :-). No hurt feelings here at all brother. Reason I came to you guys. You’ll be honest.
That tax is actually Texas taxes. Need to refund this to all. Well, except the Texas guy. :-). I’ll get all these refunds issued by the latest Monday. Silly Geozone stuff that’s a great time to play with!
And with your order believe there’s only one other dust boot in the beta batch then this all is deleted and the site goes dark to get worked on.
Thank you to all you guys! And please don’t hesitate to get a hold of the team contact@smw3d.com with comments and suggestions.
There will be a quick manual made up and sent to the builders who ordered.
