Hey Chris,
Yes, I read that when you posted it.
Wait, you contacted the manufacturer and they told you to buy a new switch, but they were not able to tell you the specification of the switch? Who can tell the specification of the switch, if not the manufacturer??
Sure, my advice is I would write to the support@onefinitycnc.com and tell the product is failing.
In my country (and in the whole EU) if the seller receives a notice of defect he has the options a) to send a replacement item b) to repair the item purchased. All costs of replacing or repairing including shipping have to be borne by the seller. If the item is still failing after the seller replaced/repaired it three times, the buyer has the right to resign the purchase contract and the seller must reimburse the buyer.
That you are told to repair something yourself seems weird. But it can be the case if something is not covered by warranty, e.g. batteries.
In my country (and in the whole EU), warranty and defects liability are not the same thing. The first is something a manufacturer can give, but the second is given by law and is mandatory for 24 monthes from date of receipt of item and is applicable to any failure if the buyer is a consumer.
You got your machine last month right? And the power switch was already failing? I don’t understand why you think you’d repair such a defect yourself.
