Uwe Posted August 5, 2015 Report Posted August 5, 2015 The needle positioning systems on these cheap servo motors mostly work by installing the sensor on the hand wheel ( easy or hard, depending on your machine). The sensor has a switch that activates when the hand wheel is in a certain position. During setup you turn the hand wheel in the desired position (usually needle down), then turn the sensor until the switch activates and the little light comes on, then tighten the set screw. The programming unit now knows which position is the down position and will stop in that position when you let go of the pedal. The programming unit usually allows you to switch between stopping in either needle up or down position with a few button presses. However, it does NOT stop wherever you start. Some systems also have the "heel" feature which gives you an additional half turn when you tilt the pedal backwards with your heel, making both up and down needle positions easily accessible. It's not so easy to turn the needle positioning OFF on the systems I have tried. I wish they had a simple three-way switch like my old Viking has (up/off/down), but unfortunately they generally use button presses to navigate a cryptic, crude menu with no OFF option. On my motors I had to unplug the sensor to turn needle positioning off. Much of the above probably does not apply to fancy setups like Efka systems etc. Quote Uwe (pronounced "OOH-vuh" ) Links: Videos
Members 276ccm Posted August 6, 2015 Author Members Report Posted August 6, 2015 Thanks for replies! :-) I got my machine today, and I think it looks good! Now I just have to decide if I´ll go for the JK, ISM or the Ho Hsing G60 motor I´m awaiting prices for. I found a company in Spain and one in France that sells them. I tested the machine today, and it works fine, but as I expected the stick length isn't really large, 6 mm at the maximum, but I´m happy with my machine so far! :-) Quote Blog: http://276ccm.blogspot.com/ Facebook: https://www.facebook.com/276ccm
Trox Posted August 8, 2015 Report Posted August 8, 2015 Hi Marius, although the Flomax 335 clone is a versatile machine, they would not preform well with any thicker thread than than Nm 40 (tex 69). Perhaps a size heavier on top, but the small bobbin will not take much of it. There are versions of the new Pfaff 335 that have a larger hook and perhaps some clones do too. Motors, I was offered the same motor as Uwe found on Ebay for free the other day. The Efka variostop is from the 1980 (and up). It's a three Phase clutch motor (380 V) with needle position, electronic clutch and brake. It has 6 to 12 pre set speeds on the pedal depended of model and was the first of its kind. Marius, you know these motors, you had the same on your 45K machine. We set that motor up with an frequency converter and it sewed just fine. I think the motor I was offered for free is still available if anybody needs it. It's in good condition but the location is Oslo, Norway (pickup only). Anyway, 200 Euro it way too expensive for that old motor. If you can buy a Ho Hsing G 60 serie 600 watt servo motor for £ 160.-, then you will have a professional motor for a good price. It has a needle position that works as it should do, and they say the low speed control are very good. That's a plain motor with needle position only, but you can add a Ho Hsing control box to it later. I did not know that was a possibility before I saw it yesterday on their YouTube channel. That means you can build on anything you want to it, just like their more expensive motor systems. That option is a game changer, for sure. Ho Hsing make top motors and are a alternative to Efka. A Japanese motor with a price that can compete with Chinese motors, that sound good to me. I have a friend that bought one for his Pfaff 345 cylinder bed, and he says it preforms well. Let us know what you decide to do.

Members 276ccm Posted August 30, 2015 Author Members Report Posted August 30, 2015 Just to follow up, I ended up with the Ho Hsing G60 motor with he needle position. I found a company in UK (AE Sewing Machines) which had the motor for a very good price. The shipping was super fast and service simply amazing. They replied very quick to all my questions.. I´m super happy with the motor, it seems to be strong and was really easy to set up. The needle position works exactly like I´m used to with my previous machines.. easy to adjust too. I feel I have fill control with the machine now.. So I can strongly recommend the Ho Hsing motor.. Thanks a lot for all replies and to Trox for your expert knowledge! :-) A little shot of my machine with the new motor :-) Quote Blog: http://276ccm.blogspot.com/ Facebook: https://www.facebook.com/276ccm
Uwe Posted August 30, 2015 Report Posted August 30, 2015 That is one beautiful looking machine - congratulation on finding such a pristine example! Nice setup with the new servo motor! Quote Uwe (pronounced "OOH-vuh" ) Links: Videos
Members Colt W Knight Posted August 30, 2015 Members Report Posted August 30, 2015 Youll be able to get some sewing done on that machine, for sure. Quote
